pipeline: EDITORIAL.md voice charter + fresh-eyes copy-edit stage

One written standard for every audience-facing word: concise, to the
point, inspiring delight through specificity — with word budgets per
copy type (reviews had drifted from a ~370-word median to 500-1000+).
All writing skills now reference the charter, and daily-pipeline gains
a stage-4 copy-edit pass: a subagent that didn't write the day's copy
tightens it against the charter, prose only, diff reviewed before
commit. Digest gains a copy-edit line.

 ## Conventions that bite
 
+- **`EDITORIAL.md` is the voice charter** — concise, to the point, inspiring delight (through specificity, never ad copy); word budgets per copy type. All audience-facing prose follows it; the pipeline runs a fresh-eyes copy-edit stage over each day's new copy.
 - **No tobacco or alcohol content** — hard editorial exclusion at every stage: never captured as finds, never selected into new bundles, never graduated to reviews. A few legacy alcohol finds (May–July 2026) stay published and keep their existing bundle spots, but they're ineligible for anything new.
 - Review heroes are auto-discovered from `src/content/reviews/<slug>/hero.<ext>` (`src/lib/hero.ts` glob) — name the file `hero.*`; no registration.
 - The homepage "pick of the day" is `src/data/pick.json` (`{"hero": "<review-slug>"}`); falls back to the latest review.
