Enable noUncheckedIndexedAccess and fix all 98 call sites it surfaced across 18 files. Every fix is behaviour-preserving — the flag flagged reads TypeScript couldn't prove in-bounds, all of which were already guarded by a length/index check, a findIndex result, or a non-empty invariant: - read-once so a ternary's narrowing sticks (Feed overrides, linkify mention); - non-null assertion AFTER an existing guard (PlayerModal/VideoEditor queue+cut-list indexing, modules step, useUndoable stacks) with a comment stating the invariant; - nullish fallback where undefined is a real possibility (GlassTuner slider ?? def, ConfigPanel active group ?? [], descriptionLinks id ?? null); - optional chaining where the entry genuinely can be absent (PlexBrowse IO entry); - a non-empty tuple type for the RELATIVE_UNITS constant (encodes "always has [0]"). The single highest-leverage fix: PlayerModal's `active` became `queue?.[index] ?? video` (always Video), clearing 34 of the 45 errors in that file at once. Verified: tsc/eslint/prettier clean, 56 vitest + 34 pytest + 17/17 e2e green (the e2e suite exercises the feed/player/channel components touched here).
