- anchor.ts: precompute line-offset index once; O(log n) binary-search offsetToLine replaces two O(n) newline-count loops. findLineForAnchor takes an optional lineOffsets param (backward compatible). - cards.ts / generation.ts: build the line-offset index once per document and thread it through all card anchor resolutions (was N cards x ~9 full-document O(n) passes -> 1 O(n) pass + N x O(log n)). - anchor.ts: ASCII-whitespace charCode fast path in normalizeWithMap, deferring to /\s/ only for non-ASCII (exact semantics preserved). - settings.ts: memoize generationFingerprint by settings object identity (WeakMap) — collapses SHA-1 + stableStringify done on every file-open. - view.ts: remove keydown listener in onClose (lifecycle leak fix). Verified: tsc, build, biome, all 28 tests, e2e smoke, branch coverage 100% (new anchor regression tests added). Deferred (higher risk / test-breaking): view full-render->surgical DOM, scroll rebind guard, cache scheduleSave timing — see notes/perf-report.md. Change-Id: I17eef347471bb8233d48164e4453d492f301eac2
