Credibility pass: sweep the workshop floor

Scoped to everything since the last pass (695307d). The residue of
fast iteration, removed: a reduced-motion media query that had
swallowed a full copy of the .faq-seal rules; doc comments orphaned
from their functions by inserted methods; the FAQ scrape's seams
(section headings run into ruling bodies under the wrong topics, a
next-page heading shipped as a ruling, an amputated "h", and rulings
filed under alphabetically-nearest strangers — Large Rock/Dagger now
lives on those cards; Book of Spells and Torquemada describe no card
in this set and are gone); the write-only aisle flag left behind by
the reverted rev 7; a linter-silenced dead destructure; a duplicated
median lookup; dead casts; and the fallback path that ignored the
apprentice's one-card draw.

Tests now typecheck (tsconfig includes test/), which surfaced the
missing type imports and a drifted creature literal hiding under an
as-cast. Also: a no-op self-assignment, mid-file imports hoisted, a
dynamic-import habit made static, a hedge comment replaced with a
loud setup failure, the fallback-retries-itself dead rung removed
from both bot drivers, and the twin peek scrims merged.

Deliberately kept: the TIERS lookup guard (ledger JSON is untrusted),
the wand-cost stanzas (they differ on the power-attack trade — a
rules question, not a dedup), and rollDie's coexistence with rollD4
(migrating changes visible logs; future work).
