Session 35: Design system Phase D — core screens: Grade Result, Slate card, Scan, Terminal, Landing (1839 tests)

VYNDR 2.0 conversion, Phase D (the screens users touch). Frontend-only; zero
backend changes.

- GradeResultCard + ProcessingGrade (the core product moment): intel-surface
  grade hero, signal breakdown, kill conditions, best-book strip, alt ladder;
  sections self-hide when empty.
- lib/gradeAdapter.js maps engine output -> §7 contract and tier-gates content
  (free teaser / analyst kill-conditions / desk alt ladder) so the new card
  doesn't give paid content away.
- Scan result wired to ProcessingGrade->GradeResultCard, preserving scan limits,
  parlay add, reads tracking, and noopener sportsbook deep-links.
- GameCard (Bloomberg best/worst line cells) built + tested.
- Terminal page replaces its stub with a real league-intelligence screen.
- Landing gets the founder-seat ClaimMeter.

Honest scope: live dashboard/Slate swap onto GameCard, scan input -> TerminalInput,
full landing rebuild, and the blurred-paywall polish (Phase G) are deferred to
keep working flows stable.

22 new tests. Backend 1818 -> 1839, 143 suites, zero regressions. Web build clean.
