Garry TanandClaude Fable 5.1 982a738663 fix(design): Aside dump script stays single-quoted; redaction gate sized to the dump cap; doctrine made consistent
- The DOM-dump Aside block was the only double-quoted `aside repl` script in
  the tree (to splice the function text), which put the agent-filled <url>
  inside a double-quoted bash string: a same-origin href carrying $(...) would
  run in the reviewer's shell when Phase 3 opened that page. The script is
  single-quoted like every other Aside script and the function text enters
  through a closed-quote segment ('"$_DUMP"'); the fallback line is
  `$B js '('"$_DUMP"')()'`. A free test pins that no rendered Aside script
  opens with a double quote.
- The persist block capped dumps at 10 MiB but ran gstack-redact with its
  1 MiB default, so every real page between the two was deleted as
  DOM_DUMP_REDACTION_BLOCKED; the gate passes --max-bytes at the dump cap and
  blocks on any exit other than clean (0) or MEDIUM (2), so a redaction tool
  that fails to run can no longer fall through to "persist".
- Dump hygiene removes <template> and <noscript> subtrees (invisible to the
  attribute walk), inline on* handlers, and the cross-origin <link> nodes
  already named in the note, so the file handed to the engine references no
  remote stylesheet.
- Doctrine: the Codex design-voice prompts said "2-3 intentional motions"
  against the one-authored-moment rule; the overused-display heading scoped
  its ban to Persuade/Experience while the catalog and hard rules ban it
  everywhere; design-consultation's Important Rule 4 still said "as primary";
  design-html's blacklist header is now "Never include by default" with the
  mockup/DESIGN.md/user-ask override the catalog grants; the slop gate honors
  Decisions Log and Do's and Don'ts blessings like /review does; the landing
  "poster" line says poster in stance, not type size; the design binary's
  variant dials no longer flip light/dark for variety; gstack's DESIGN.md
  rows name data labels (UI labels stay the DM Sans token) and call the
  skill-bar fill and hovers functional transitions.
- design-review names how the base branch is found (gh pr view, then the
  repo default; never main) for the source-mode scan and the diff-aware mode.
- frontend-scope matches the config globs at the repo root only, like the
  bash arm; the parity test carries nested samples.
- Cleanups: renderCatalog's stale style option, an unused import, the
  identity-map bannedFontNames, the checklist header's "same entries" claim,
  the catalog header's consumer list, the orphaned main() docstring, the
  plan doc's IIFE bullet. design-html's skeleton ceiling is re-measured
  (54,184) for the two doctrine sentences.

Tests: AUTO-FIX rendering from the catalog, the E2E slice markers checked in
the free suite, the hygiene cases for templates/noscript/handlers/remote
links, and the review E2E counting detector rows separately from the seven
checklist plants.
