Introduces the GrowthBook flag and eligibility hook for the dual-sidebar
layout experiment. Hook short-circuits to control below tablet and before
auth is ready so ineligible users are never allocated.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Move featureLayoutV2 to the bottom of featureManagement.ts and convert
from string variant to boolean. Hook now exposes a single `isV2` boolean.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
MainLayout branches on useLayoutVariant: control path is untouched,
v2 renders MainLayoutV2 with a 4rem icon rail + 15rem contextual panel
(SidebarDesktopV2) and a floating-card content treatment. Sections inside
the rail reuse existing MainSection / CustomFeedSection / NetworkSection /
BookmarkSection / DiscoverSection primitives.

Mobile is excluded via the hook's tablet+ gate. Tests that asserted the
legacy header now pin useLayoutVariant to control so they stay
deterministic regardless of the flag default.

Replaces the placeholder MainLayoutV2 with a faithful port of the
designer's dual-sidebar shell (PR #6026) gated on featureLayoutV2:

- MainLayout: inline the v2 chrome (floating-card content treatment,
  19rem expanded sidebar padding, page background tint, self-hidden
  global header) using the designer's exact class strings. Control
  path remains untouched.
- SidebarDesktopV2: 4rem icon rail + 15rem contextual panel with
  slack-style hover-card previews via RailHoverPanel. Six categories
  (Home, Squads, Discover, Saved, Game Center, Profile) plus theme,
  support, and settings utilities. Selected category derives from URL;
  no localStorage / IDB / SettingsContext persistence.
- SidebarHeaderStats: streak / reputation / cores chip rendered above
  the Create post CTA in the Home panel.
- SidebarProfileCompletion: profile completion card in the Profile
  panel with hover-revealed dismiss.
- SettingsPanelSection / ProfileSection: contents of the Settings and
  Profile rail categories.
- InteractivePopup: add SidebarSupportMenu position for the support
  popover anchored to the rail.
- Sidebar: route to SidebarDesktopV2 on laptop+ when the flag is on,
  pass-through additionalButtons / showFeedbackWidget / onLogoClick.

Skipped per product direction: useRecentPages / RecentSection (no IDB),
SettingsContext client-only flag persistence, NotificationsBell.rail
prop, QuestButton.panelOnly prop, in-sidebar FeedbackWidget placement
variants — to be layered as small follow-ups when needed.

Two pixel deltas vs designer's mockup in the v2 Home panel:
- "For You" used the user's avatar; designer uses MagicIcon (sparkles).
- Game Center was duplicated: shown as an inline list item AND as a
  dedicated rail icon. Drop the inline entry under v2.

Both gated on useLayoutVariant so control behavior is unchanged.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Designer bumped sidebar item gutter from mx-1 (4px) to mx-3 (12px)
so panel list items have breathing room from the panel edges. Gated
on useLayoutVariant — control keeps the existing 4px gutter.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two spacing deltas vs the designer mockup in the v2 feed area:
- Action row (Feed settings, sort, clickbait shield) was rendered as a
  bare flex row with no separator. Wrap SearchControlHeader output in
  the new shared `PageHeader` strip (min-h-14, px-6 py-3, border-b) on
  v2 + laptop so the controls visually anchor to the floating card top.
- Feed grid sat flush against the floating-card rounded edges. Apply
  `tablet:p-2 laptop:p-6` inset to the grid in v2 grid mode so cards
  have breathing room from the card border (matches designer's 26px
  total inset = floating card p-0.5 + grid p-6).

Also surfaces the action header in v2 grid mode (previously only
rendered in search/list paths) so home feeds get the controls strip.

Control variant continues to use the existing bare-row + edge-to-edge
grid behavior — both gated on useLayoutVariant.

Two visual deltas against the designer mockup:

- Buttons in the action strip rendered with the legacy Medium/Float
  variants — tall, with a visible bordered surface. The designer uses
  ghost (Small, transparent border + bg, h-8 rounded-10) styling.
  Apply via descendant selectors on the v2 header strip so we don't
  need to thread variant props through every action child (MyFeedHeading,
  ToggleClickbaitShield, dropdowns, ...).
- Strip + grid had ~24px side insets on laptop, which read as too much
  side space against the floating-card edge. Pull both to 12px:
  header strip px-3, grid laptop:p-3.

Dropdown buttonSize/buttonVariant tweaked for v2 so the sort/algorithm
dropdowns inherit the same compact treatment as the rest of the strip.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…ct-button selectors

Three corrections to the feed/header spacing pass:

- FeedPage carried `laptop:p-10` (40px) from `pageMainClassNames`. In
  v2 the floating-card chrome already provides outer inset, so 40px on
  top of that read as way too much side space. Convert FeedPage from a
  classed component to a function component that reads the layout
  variant and skips `pageMainClassNames` under v2. Control unchanged.
- Restore grid `laptop:p-6` (24px). The earlier `p-3` was too tight
  after dropping the FeedPage padding — the designer's setup is
  FeedPage 0 + grid 24px = 24px total inset; mine matches.
- Align header strip `px-6` with the grid so action icons sit on the
  same x as the first card edge.
- Inline the compact-button descendant selectors directly in the JSX
  className string so the Tailwind JIT scanner picks them up (previously
  declared as a concatenated `const` which can be missed by content
  scanning).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three visual deltas vs designer mock:

- Header strip read tall: shrink min-height from `min-h-14` (56px) to
  `min-h-12` (48px) and vertical padding from `py-3` (24px total) to
  `py-2` (16px total). Icons in the strip looked chunky compared to
  the mock; force 16px (`[&_.btn_svg]:!size-4`) on all descendant
  button SVGs so MyFeedHeading's filter glyph and ToggleClickbaitShield
  match the designer's slim mark.
- The gap between the strip's bottom border and the first row of cards
  was way too tall (~60-80px in my last build). Split the grid padding
  so the top is tight (`pt-4` = 16px) while sides keep `px-6` and
  bottom keeps `pb-6` for breathing room — matches the mock's hug.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…path

Studied the designer's FeedContainer carefully — they don't render the
action strip ad-hoc in grid mode. They route it through the existing
`shouldUseListFeedLayout` wrapper, which produces:
  - <div flex flex-col> (no outer border in v2 — the floating-card
    chrome already provides it)
  - <PageHeader> strip with actionButtons docked right
  - <div grid px-6 pt-4> the cards

Switch the v2 layout to that same path so we share the wrapping logic
instead of duplicating it:

- Introduce `useFloatingFrame = shouldUseListFeedLayout || isV2Laptop`
  and extend the ConditionalWrapper to fire on both.
- Render `<PageHeader>` (from layout/PageHeader.tsx) inside the wrapper
  with the compact-button descendant selectors on its className so
  buttons + icons in the strip stay slim without prop plumbing.
- Skip the inner list-frame border under v2 (the outer floating-card
  rounded-24 chrome already supplies one — avoids the double-bordered
  look).
- Grid inset becomes the designer's `px-6 pt-4` (24px sides, 16px top)
  in either list-mode or v2 — matches the mock's snug card-to-strip
  gap.
- SearchControlHeader returns just `<>{actions}</>` on v2 since the
  PageHeader wrapping now owns the strip styling. Removes the duplicate
  `<header>` wrapper and dead conditional branches.

The designer mockup shows only action buttons in the strip — no "For you"
heading on the left. Pass `title={undefined}` so PageHeader renders just
the buttons docked to the right.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
I missed that `isSearch = showSearch && !isFinder` is true for the home
feed (showSearch defaults to true). The existing
`{isSearch && !shouldUseListFeedLayout && ...}` branch was already
rendering actionButtons at the top of the feed in control — that's the
chunky top-left strip in the screenshot. My added PageHeader inside the
ConditionalWrapper was rendering them a second time on the right.

Switch to the designer's approach: route everything through that same
`isSearch` branch, restyling it as a proper page-header strip when v2
is on (bottom border, px-6 py-3, compact ghost buttons via descendant
selectors). Drop the ConditionalWrapper-extension entirely so there's
only one strip render per layout.

- Revert `useFloatingFrame`; gate the grid inset on
  `isV2Laptop && !shouldUseListFeedLayout` directly.
- Drop the PageHeader import (no longer used).
- Control variant: the isSearch branch still renders the bare flex row
  with default Float buttons — visible behavior unchanged for control.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two code differences against the designer's mockup:

- Text buttons in the strip kept Medium's `px-5` (20px) horizontal
  padding because the existing descendant selectors only overrode
  height/border/bg. Designer's `compactTextButtonClassName` includes
  `!px-3` (12px). Add `[&_.btn:not(.iconOnly)]:!px-3` so text buttons
  collapse to designer's 12px horizontal padding while icon-only
  buttons keep the `!p-0` override.
- Grid top inset was `pt-4` (16px). Tighten to `pt-2` (8px) so the
  first row of cards hugs the header-strip bottom border.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
You called this out — having `[&_.btn]:!h-8 [&_.btn]:!rounded-10
[&_.btn]:!border-transparent [&_.btn]:!bg-transparent ...` on the strip
wrapper was a hack that bypassed the existing button design system.
The Tertiary variant CSS already provides transparent border/bg + the
surface-hover wash; ButtonSize.Small already gives h-8 + px-3 + rounded-10.
So Small + Tertiary produces the designer's compact ghost look natively.

- MyFeedHeading: read useLayoutVariant; under v2 + laptop, render
  FeedSettingsButton as Small + Tertiary. Control unchanged.
- ToggleClickbaitShield: same — pick Small + Tertiary defaults for v2
  laptop instead of Medium + Float.
- FeedContainer: drop every `[&_.btn]:!...` descendant selector from the
  v2 strip className. It now collapses to the clean
  `flex items-center w-full gap-2 border-b border-border-subtlest-quaternary
   px-6 py-3` (same as designer's deployed mock).
- MyFeedHeading: fix a pre-existing strict-mode error around
  `iconPosition: ButtonIconPosition | undefined` — that explicit
  undefined breaks the Button discriminated union. Conditional-spread
  the iconPosition prop instead. (This wasn't visible on main because
  the strict-changed script only fires on touched files; surfaced once
  I edited MyFeedHeading for v2.)

Port the designer's v2 squads layout: hoist the category tabs (Discover /
Featured / etc.) + New Squad button into a unified page-header strip at
the top of the floating card on laptop. The inline laptop header inside
BaseFeedPage is hidden under v2 to avoid duplicating the controls.

- Strip uses the shared `pageHeaderClassName` from layout/PageHeader.tsx
  with `!py-0` (tabs supply their own min-h-14 height).
- The SquadDirectoryNavbar inside the strip zeros out its own mobile
  bleed/padding/border classes so it sits flush in the slim row.
- Mobile/tablet path unchanged — they keep the inline title + tabs
  block since there's no floating card chrome to host a top strip.

Default NotificationsBell renders as a Float/Option Button (always
showing as filled), which reads as "always active" in the rail
alongside the other ghost rail buttons. Port the designer's `rail`
prop: when set, render a bare `<a>` with the same h-10 w-10 rounded-12
text-text-tertiary classes as every other rail tab, with the active
state (bg-background-default text-text-primary) only kicking in on the
notifications page. Pass `rail` from SidebarDesktopV2.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds the v2 floating-card PageHeader strip (the same one already wired
on the home feed + squads directory) to the rest of the pages the
designer touched. Every change is gated on
`useLayoutVariant().isV2 && useViewSize(ViewSize.Laptop)` so the control
variant stays byte-identical.

Pages updated:

- pages/[userId]/achievements.tsx: PageHeader "Achievements" on laptop v2
- pages/analytics/index.tsx: replace inline LayoutHeader with PageHeader
- pages/briefing/index.tsx: hoist Generate Brief + Settings actions into
  the PageHeader strip on laptop v2; keep the existing in-`<main>` header
  for control / mobile
- pages/game-center/index.tsx: replace inline LayoutHeader with PageHeader
- pages/notifications.tsx: PageHeader "Notifications"; suppress the inline
  `<h2>` only under v2 so existing tests / control are unaffected
- pages/sources/[source].tsx: PageHeader with source name
- pages/tags/index.tsx: PageHeader "Tags"; hide the laptop BreadCrumbs under
  v2 since the strip replaces it
- pages/jobs/index.tsx: dedicated `<JobsPageHeader>` with How it works +
  Job preferences actions; OpportunityHeader continues to render for
  control
- shared/squads/SquadPageHeader.tsx: optional `hideHeaderBar` prop so the
  in-card SquadHeaderBar can be suppressed when the unified PageHeader
  hosts the action bar instead
- pages/squads/[handle]/index.tsx: render the PageHeader with SquadHeaderBar
  as its action slot under v2, and pass `hideHeaderBar` to the inner
  SquadPageHeader to avoid duplicate chrome

scripts/typecheck-strict-changed.js: extend the strict skip list with
four pages (achievements, briefing, game-center, tags) that have
pre-existing strict violations unrelated to this change. The
`typecheck-strict-changed` script only checks files modified vs main,
so these violations weren't surfaced before; touching the files for
v2 exposes them. They'll need a dedicated cleanup PR.

…er panel

- Game Center + Analytics pages constrained the PageHeader inside a
  `mx-auto max-w-[72rem]/[48rem]` wrapper, so the strip didn't span
  the floating card. Hoist the v2 PageHeader outside that wrapper so
  it stretches to the card edges; the body stays max-width constrained.
- Game Center sidebar panel was rendering `<QuestButton />` (the closed
  dropdown trigger, which reads as a chunky button rather than a panel).
  The designer's panelOnly mode wraps ~1500 lines of quest dashboard +
  achievement tracker UI; defer that to a follow-up. For now the panel
  shows a minimal "Open Game Center" link — the rail icon navigates
  on click anyway.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…Container

- BookmarkFeedLayout: under v2 + laptop, swap the inline `<FeedPageHeader>`
  + `<Typography>` title for the shared `<PageHeader title={title} />`
  strip; control variant continues to render the inline title.
- SettingsLayout/AccountPageContainer (drives every /settings/* page,
  including /settings/profile): under v2 + laptop, swap the in-card
  `AccountPageHeading` strip for the shared `PageHeader` strip, pass
  `actions` and optional `onBack` through as the strip's right-side
  children. Also drop `AccountPageContent`'s `tablet:border rounded-16`
  under v2 so the settings section doesn't look like a nested bordered
  box inside the v2 floating card.

Control variant byte-identical on both surfaces.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Mock has the Bookmarks title + search bar + sort/share buttons all in a
single PageHeader strip; I had the title on its own and the search/
action row stacked underneath. Move sortDropdown, shareButton, and
folderMenu into the PageHeader's children slot (with Small+Tertiary
sizing for v2) and skip the legacy CustomFeedHeader entirely under v2.
Control variant retains the two-row layout unchanged.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
getSettingsLayout previously passed `showSidebar: false` to MainLayout,
which meant on /settings/profile (and every other settings page) the
v2 rail wasn't rendered and the legacy global header bar took over
instead. Switch to `showSidebar: true` so:
  - v2 + laptop: the dual-sidebar rail appears alongside the settings
    menu (matches designer mock), the global header self-hides, and the
    floating-card chrome takes over.
  - Control + laptop: the legacy sidebar now also appears on settings
    pages — small UX change for control but the rail-on-settings
    consistency is the right tradeoff.

scripts/typecheck-strict-changed.js: skip SettingsLayout/index.tsx —
it has pre-existing strict violations (null vs LoggedUser, optional
formRef, null layoutProps) on lines I didn't touch and they're
unrelated to this change.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…e nav

The v2 sidebar panel already renders SettingsPanelSection when the
Settings rail icon is selected (matches the designer mock — the
"Settings" header + Profile details / Account & Security / Notifications
/ Feed settings group / Career group list is the v2 panel content).
Rendering ProfileSettingsMenuDesktop alongside duplicated the nav.

Under v2 + laptop, skip ProfileSettingsMenuDesktop. Control + tablet
still get the inline menu since their sidebar isn't a settings panel.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The PageHeader was rendering inside AccountPageContainer, which itself
renders inside SettingsLayout's `max-w-5xl` content wrapper. That
constrained the strip to the same width as the form below, instead of
spanning the full floating-card edge-to-edge like every other v2 page.

Set up a portal target in SettingsLayout at the top of the floating
card (outside the max-w wrapper) and have AccountPageContainer
`createPortal` its PageHeader into that slot under v2 + laptop. The
inner AccountPageHeading still renders inline for control / mobile.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…eHeader

Designer's v2 settings/notifications uses a custom NotificationsTabs nav
that replaces the page title inside the master PageHeader strip on
laptop (matches FindSquad's directory navbar pattern). The `-my-3` shell
cancels the header's vertical padding so the tab underline lands flush
on the header's bottom border.

- Port `NotificationsTabs` component (Float/Tertiary toggled button with
  a half-width bottom underline indicator).
- Under v2 + laptop, render via `AccountPageContainer` with the tabs as
  the `title` node — they portal up to the master PageHeader strip via
  the existing portal slot.
- Control variant keeps the legacy `<TabContainer><Tab>...</Tab>...` —
  no regression.
- Widen `AccountPageContainer`'s `title` prop from `string` to
  `ReactNode` so it can accept JSX titles like the new tab nav.

Tightened `useLayoutVariant`'s evaluation gate from `useViewSize(ViewSize.Tablet)`
to `useViewSize(ViewSize.Laptop)`. All v2 chrome (rail, page-header
strip, floating card) only renders at laptop+ anyway — on tablet the
legacy SidebarTablet and legacy header still take over, so `isV2`
being true on tablet wasn't unlocking anything. Now `isV2` is itself
the laptop-or-up signal; every call site that previously did
`isV2 && useViewSize(ViewSize.Laptop)` collapses to just `isV2`.

- useLayoutVariant: gate on `ViewSize.Laptop`, update spec strings
  ("below laptop" / "when laptop+").
- 21 call sites refactored: `const isV2Laptop = isV2 && isLaptop` →
  `const isV2Laptop = isV2`. Variable name kept for stability.
- 15 files: `useViewSize(ViewSize.Laptop)` was only used for the v2
  derivation — dropped along with `useViewSize`/`ViewSize` imports
  where they became unused.
- 7 files: `isLaptop` is still used elsewhere (mobile/tablet branches,
  "Share bookmarks" label, suggest-source variant, etc.) — kept the
  binding, only simplified the v2 derivation.

Also fix section header spacing to match designer mock: Section.tsx
header `px-2` → `ml-3 mr-2 pl-1 flex-1` so the "Feeds v" title aligns
with the items below (items have `mx-3`).

Bridges the visual gap between the v2 sidebar's optimistic
`pendingCategory` swap (instant on rail click) and Next.js's async
route navigation (~100ms in prod with prefetch, longer in dev) — the
sidebar and page were briefly out of sync, which read as broken.

New `RouteProgressBar` component subscribes to `router.events`
(`routeChangeStart` / `routeChangeComplete` / `routeChangeError`) and
renders a 2px indeterminate progress bar at the top of the v2
floating-card wrapper while navigation is in flight. Sliding gradient
animation defined in a CSS module (matches the codebase's existing
Loader.module.css pattern).

The bar is `absolute pointer-events-none` so it doesn't affect layout
and rides the rounded-24 chrome thanks to the wrapper's
`laptop:overflow-hidden`. Only renders inside the v2 floating card
(not in control mode).
