docs(convoys): unify-glass-panel-surfaces + cleanup palette — conductor seed + architect plan (#119)
* docs(convoys): seed unify-glass-panel-surfaces + cleanup-card-item-list-and-share-modal-palette

Two convoy seeds opened as follow-ups to the 2026-06-04 design pass
(#116 corner-border-light → #117 site-wide sweep → #118 card vibrancy
reduction). Both were called out in #117's PR body as deferred and are
now formally tracked.

## unify-glass-panel-surfaces

Migrates remaining panel-shaped surfaces to the gradient-border
corner-light treatment so the app shares one surface vocabulary.

The audit's key insight: `<GlassSurface>` (`components/ui/GlassSurface.js`)
predates the corner-light pattern. Because `<Modal>`, `<StatCard>`,
and the landing-page feature/collection cards all delegate to it,
upgrading the primitive cascades to ~10 visible surfaces at once.

7 briefs, multitask-parallel after Brief 1 lands:

1. `<GlassSurface>` primitive upgrade — BLOCKING for 3, 4
2. Auth form cards (login.js, signup.js)
3. Floating popovers (mobile drawer, sidebar profile dropdown,
   UserMenu dropdown)
4. BulkSelectionToolbar (currently `bg-white border-gray-200` —
   invisible in dark mode)
5. `.card`-class consumers (4 pages); decision to ratify whether
   to retire `.card` entirely or keep as documented opaque fallback
6. Landing nav bar — wrong pattern; should use existing
   `.page-header-glass` class
7. `forbidden-bespoke-glass-surface` CI grep gate — prevents
   regression after the migration ships

## cleanup-card-item-list-and-share-modal-palette

Targeted palette cleanup for two files whose interiors weren't
addressed in #117:

1. `CardItem.js` list-mode (L183–284) — entirely hardcoded
   Tailwind palette (`bg-purple-50`, `border-gray-200`, `text-gray-{500-900}`,
   `bg-blue-100 text-blue-800` etc.); unreadable / off-brand in dark mode.
2. `ShareModal.js` interior rows — purple avatar circles, gray-50
   permission row (invisible in dark mode), blue-600 Copy-link button,
   gray text labels.

Token-only swap. 2 parallel briefs, no architect / IA / UX needed
(no design decisions — palette to design tokens).

## Sequencing note

The two convoys are independent and can run in parallel. The audit
agent's recommended sequencing (Brief 1 of `unify-glass-panel-surfaces`
first) is encoded in the multitask `slice_dependencies` blocks.

* docs(convoys): architect plan + 7 briefs for unify-glass-panel-surfaces

Appends the ## Architecture section to .convoys/unify-glass-panel-surfaces.md
ratifying the 4 open Decisions, and writes 7 implementer-brief files under
.convoys/unify-glass-panel-surfaces/.

Decisions ratified:
  D1. <GlassSurface> grows a cornerLights='subtle'|'chrome'|'none' prop,
      default 'subtle' (4-layer gradient-border per PR #118 recipe).
  D2. Retire .card entirely; migrate all 8 consumers to .glass-panel.
  D3. Mobile drawer uses subtle tier (.glass-panel-strong).
  D4. CI gate scopes to JSX inline-style usage only; 3-entry allowlist
      for documented chrome exceptions.

Briefs (1-7, all <100 LOC each, disjoint files):
  1. Upgrade <GlassSurface> primitive (no deps, blocks 3+4)
  2. Migrate auth form cards (parallel-safe)
  3. Migrate floating popovers (sidebar dropdown, mobile drawer,
     TopSearchBar UserMenu)
  4. Migrate BulkSelectionToolbar + interior token sweep
  5. Retire .card class; migrate 8 consumers
  6. Migrate landing nav bar to .page-header-glass
  7. forbidden-bespoke-glass-surface CI gate (runs LAST)

Boot-the-brief check: all 4-layer recipes verified against post-PR-#118
styles/globals.css; all box-shadow preservation chains verified against
current Layout.js + TopSearchBar.js; .card deletion verified clean
(single rule at L729-733); CI gate shape modeled on existing
forbidden-modal-shell-without-primitive job.

Architecture is read-only output — no application code touched.
Awaiting human gate 1 (plan approval) before implementers run.

* docs(convoys): fix Brief 3 TopSearchBar UserMenu elevation token

Self-review recheck against current TopSearchBar.js (L211-222) found
that the UserMenu dropdown uses var(--elevation-pronounced), not
var(--elevation-ambient) as Brief 3's initial sample showed. Brief 3
now documents the verbatim shape (pronounced + role="menu" +
aria-label + overflow-hidden) and the convoy's risk-list note is
updated to reflect all three popovers' verbatim chains.

No semantic change to the plan; just an accuracy fix the
implementer of Brief 3 needs to ship the right code on the first try.

# Brief 6: Migrate landing nav bar to `.page-header-glass`
## Goal (1 sentence)
Replace the handrolled translucent `<nav>` on the public landing page with the canonical `.page-header-glass border-b` className, and drop the malformed `boxShadow: 'inset 0 1px 0 var(--rim-light-inner)'` (the token already contains its own `inset 0 1px 0`; double-wrapping breaks the cascade — documented in `styles/globals.css` L748-761).
## Files in scope (do not edit anything else)
- `pages/index.js` — the landing `<nav>` block, currently L61-72 (around the `border-b` declaration with inline `background: 'var(--glass-surface-mid)'` + `backdropFilter` + `boxShadow: 'inset 0 1px 0 var(--rim-light-inner)'`).
**Out of scope:** everything else on the landing page (the Deck Hearth heading, the Sign In / Get Started buttons inside the nav, the hero section, feature cards, footer, the `if (user) return null;` redirect logic, etc.). The migration is a single `<nav>` element's `className` + `style` swap.
## Conventions to follow
- **Verbatim replacement:**
```jsx
// Before:
<nav
className="border-b"
style={{
background: 'var(--glass-surface-mid)',
backdropFilter:
'blur(var(--glass-blur-mid)) saturate(var(--glass-saturate))',
WebkitBackdropFilter:
'blur(var(--glass-blur-mid)) saturate(var(--glass-saturate))',
borderColor: 'var(--border)',
boxShadow: 'inset 0 1px 0 var(--rim-light-inner)',
}}
>
// After:
<nav
className="page-header-glass border-b"
style={{
borderColor: 'var(--border)',
}}
>
```
The class provides `background`, `backdrop-filter`, and the
correct `box-shadow` (which IS `var(--rim-light-inner), 0 1px 0
var(--border)` per its definition in `globals.css` L300-306). The
`border-b` Tailwind class needs the `borderColor` style to remain
themed; everything else collapses into the class.
- **The malformed boxShadow is the bug:** `var(--rim-light-inner)` is
already a complete `inset 0 1px 0 <color>` declaration. Wrapping
it in another `inset 0 1px 0 ...` produces invalid CSS that the
browser silently drops. The class's own `box-shadow:
var(--rim-light-inner), 0 1px 0 var(--border)` does the right
thing. Removing the inline `boxShadow` line is the fix.
- **Children verbatim:** the `<div className="max-w-7xl mx-auto ...">`
inside the `<nav>`, the `<AnimatedFireLogo>`, the heading, and the
Sign In / Get Started buttons all stay byte-identical. Do not
touch them.
- **`.page-header-glass` placement check:** the class is defined in
`styles/globals.css` L300-306 and is already used by authenticated
pages' header strips (dashboard, my-cards, cards, etc.). It's safe
to reuse on the public landing page the class has no auth
coupling.
- **Nested backdrop-filter check** (boot-the-brief risk #6): the
landing page has no enclosing Layout (the `pages/index.js` redirect
logic returns `null` for authenticated users and renders its own
full-page `<div>` for anonymous visitors no `<Layout>` wrapper).
So there's no risk of nested `backdrop-filter` stacking. Verified.
- **AGENTS.md / no-go zones:** `pages/index.js` is an authored page,
not a generated artifact. Allowed.
## Acceptance criteria
- [ ] Landing `<nav>` uses `className="page-header-glass border-b"`.
- [ ] Inline `style` on the `<nav>` retains only `borderColor: 'var(--border)'` no `background`, no `backdropFilter`, no `WebkitBackdropFilter`, no `boxShadow`.
- [ ] The Deck Hearth heading + Sign In / Get Started buttons inside the nav render identically.
- [ ] Manual: open `/` in an incognito window (anonymous user), verify the nav bar renders with a subtle glassy treatment, an `inset 0 1px 0` highlight (the inner rim), and a 1px bottom border. Verify in both light and dark theme via the theme toggle (which appears on the public landing). Attach light + dark screenshots to PR.
- [ ] `npm run lint` + `npm run test:run` pass (no test count change expected).
- [ ] No edits to other files.
## Rationale (≤3 sentences)
The landing nav is the highest-visibility public surface in the app and currently both (a) duplicates `.page-header-glass`'s composition handrolled, and (b) ships a malformed `boxShadow` that silently breaks. Migrating to the canonical class is a one-line cleanup that fixes a latent bug. No corner-light treatment is appropriate here the nav is full-bleed, so corner radials would land at viewport edges and never read as light sources; `.page-header-glass` (which uses the rim/border-only composition) is the right shape.
