refactor(for-you): bring FeedCard into vellum-coherent design alongside storytelling cards

Per founder dispatch 2026-05-14 (qitem-20260515025211-b78ef3b2 +
spec doc for-you-feedcard-redesign-spec-2026-05-14.md). Closes the
visual-inconsistency where /for-you rendered two card systems
side-by-side (storytelling cards in the new vellum chrome above,
queue-item FeedCard.tsx in the old chrome below).

PURE refactor — no API changes, no removed rich content. Only the
chrome around the existing rendering changes.

CHANGES PER SPEC:

1. Outer chrome — replaced VellumCard + KIND_ACCENT/TONE_ACCENT
   left-stripe with the vellum recipe used by CardShell:
     bg-stone-100/45 + backdrop-blur-[10px] + ambient 3-stop box-shadow
     + 4 CornerBracket marks imported from ../dashboard/vellum/index.js
   No left-stripe; no outline border. The 3-stop shadow defines card
   edges through the vellum surface.

2. Kind indicator — replaced KIND_TOKEN + TONE_TEXT colored-pill
   chrome with mono+leading-dot pattern. New KIND_DOT map binds
   each FeedCardKind to a design token (bg-tertiary / bg-warning /
   bg-success / bg-secondary / bg-stone-500). New TONE_DOT map does
   the same for ProjectMetaTone. Off-brand utilities (bg-emerald-50,
   bg-rose-50, bg-amber-50, text-emerald-800, etc.) are gone.

3. Typography bump — title goes to font-headline text-[16px] font-bold
   leading-tight (was font-mono text-sm). Body / hint copy goes to
   font-body text-[12px] leading-relaxed (was 11px). Legibility north
   star: For You is the human attention queue.

4. VerbActions buttons — vellum-style bordered-no-fill with hover-
   invert. min-h-[44px] touch target. Design-token mapping:
     approve  → border-success    / hover bg-success
     deny     → border-tertiary   / hover bg-tertiary
     route    → border-stone-700  / hover bg-stone-900
     hold     → border-warning    / hover bg-warning
     drop     → border-stone-700  / hover bg-stone-900
     annotate → border-stone-700  / hover bg-stone-900
     handoff  → border-stone-700  / hover bg-stone-900
   Active state inverts to filled. mono text-[10px] uppercase
   tracking-[0.12em].

5. TONE_RECEIPT strip — replaced per-tone bg/border/text recipe (each
   tone had its own off-brand color block) with vellum-coherent
   pattern: subtle bg-stone-50/40 on all tones + a leading colored dot
   (TONE_DOT) indicates the tone. The strip stays readable and small;
   tone is conveyed by the dot, not the whole strip.

6. PRESERVED rich content — all of these render exactly as before,
   just inside the new chrome:
     ProofThumbnailGrid (proof packet image thumbnails)
     ProofPacketHeader
     ProofImageViewer (image lightbox)
     QueueItemTrigger drawer integration
     AuthorAgentTag
     formatFriendlyDate timestamps
     compactSessionLabel session display
     eventToken / queueStateToken / actionVerbToken data tokens
     TagPill (unchanged)
     ActionOutcomePanel (restyled receipt; same data shape)
     All data-testid attributes intact
     All data props + interfaces unchanged

ALSO: VerbActions.tsx in packages/ui/src/components/mission-control/
components/ was the only consumer of the per-verb color recipe.
Refactored its verbToneClass map to the design-token bordered-no-fill
pattern + bumped the button min-h to 44px touch-target.

TESTS:

test/slice-16-typography-vellum.test.tsx — replaced 4 stale source-
level assertions (old VellumCard + bg-white/35 + 11px body) with 7
new ones covering the vellum-coherent shape:
  1. Outer chrome uses bg-stone-100/45 + backdrop-blur-[10px] (no
     VellumCard; no border-l-4 left-stripe; CARD_SHADOW_STYLE +
     3-stop shadow values present)
  2. CornerBracket imported from dashboard/vellum barrel
  3. Title is 16px font-headline bold
  4. Qitem body paragraph is 12px font-body (negate old shape)
  5. ActionOutcomePanel sentence stays 12px font-body
  6. Your turn hint is 12px font-body (bumped from 11px)
  7. KIND_DOT map uses design-token colors; old colored-pill
     utilities (bg-emerald-50 / bg-rose-50 / bg-amber-50 /
     text-emerald-800 / etc) are ABSENT

Verification:
- 47/47 focused tests pass across slice-16-typography-vellum +
  feed-card-dismiss + storytelling-cards + storytelling-feed-adapter
  + storytelling-wires
- pnpm tsc --noEmit clean on touched files (pre-existing
  @tanstack/react-table errors in unrelated files unchanged from main)
- Full UI suite at baseline: 824 pass + 1 skipped + 53 pre-existing
  fails (banked AppShell global-polls + vite:css @xyflow/react carry-
  forward; orthogonal to this refactor)

LINE-COUNT IMPACT:
- FeedCard.tsx: 507 → 442 (-65 lines from dropping 4 stale chrome maps
  + simplifying receipt panels via TONE_DOT shared map)
- VerbActions.tsx: 258 → 263 (+5 lines from longer comments)
- slice-16-typography-vellum.test.tsx: 59 → 81 (+22 from 4→7 tests)

FOLLOW-ON FLAG FOR ORCH:

The dispatch states "storytelling cards (top, redesigned this
session) use the new vellum chrome". On inspection at the dispatch's
base commit, storytelling-cards.tsx (CardShell) still uses the OLD
chrome (border + bg-white/35 hard-shadow + colored pills with
bg-emerald-50 / etc). The redesign of storytelling-cards.tsx that
the dispatch references has not landed on any branch I can find via
`git log --oneline --all`. After this commit, the inversion will be
visible on the live VM: FeedCard will be vellum-coherent; storytelling
cards will still be old.

Per the dispatch's explicit OUT OF SCOPE ("Storytelling-cards.tsx
(already done)"), I did NOT modify storytelling-cards.tsx. Flagging
for orch routing: storytelling-cards.tsx likely needs a follow-up
slice to apply the same vellum-coherent pattern (CardShell can be
swapped to the same vellum recipe; ACCENTS map collapses to a
KIND_DOT-shaped table).

POST-HANDBACK GATE PLAN (per dispatch):
- Gate 1: orch reviews file structure / tests / no regression
- Gate 2: velocity-qa spins up seeded /for-you + captures screenshot
- Gate 3: design-reviewer reviews screenshot, approves or iterates
- Only merge AFTER design-reviewer approval

-// Slice 16 regression tests — typography + vellum enforcement.
+// Slice 16 typography + vellum density assertions for FeedCard.
 //
-// DESIGN.md §Typography contract:
-//   font-body Inter → prose (qitem bodies, narratives, descriptions, notes,
-//                            markdown body content)
-//   font-mono JetBrains → metadata (IDs, queue state, timestamps, tags,
-//                                   terminal/transcript, labels, chips)
-//
-// DESIGN.md §Vellum contract:
-//   bg-white/25 – bg-white/40 + paper-grid backdrop visible.
-//
-// These source-scan tests fail at CI if a future contributor re-introduces
-// the prose-as-mono pattern on the surfaces this slice fixed. Paths
-// anchored via fileURLToPath(import.meta.url) so the test runs from any
-// cwd (repo root, packages/ui, IDE test runner) per banked convention.
+// Updated 2026-05-14 for the FeedCard vellum-coherent refactor per
+// for-you-feedcard-redesign-spec-2026-05-14.md. The chrome moved from
+// VellumCard + bg-white/35 to the vellum recipe (bg-stone-100/45 +
+// backdrop-blur-[10px] + ambient 3-stop box-shadow + 4 CornerBrackets)
+// and prose body sizes bumped to 12px per the legibility north star.
