UI pass: rating widget, issue section headers, ratings verdict column

Finishes the Codex partial (0cdc302) after seeing it rendered.

Rating widget
- Inactive segments go text-ink-2 (ink on hover) so the group recedes
  beside serif body copy; the per-verdict tint stays the only colour.
- Hit area: the ::after overlay is positioned against the padding box,
  so -inset-y-1/-1.5 only gave 37/41 px. Now -inset-y-1.5/-2 -> 41 px
  desktop, 45 px phone.
- focus-visible hugs the segment (z-20, ring-offset-0); the inherited
  ring-offset-2 painted a detached box over the neighbouring buttons.
- The note field is a quiet bottom-hairline input everywhere (rule at
  rest, ink on focus) instead of a box on reader pages and an invisible
  border in tables.

Issue section headers
- The Brief, every section name and Colophon now use one serif
  uppercase, letter-spaced mark on a double rule. A sentence-case
  text-2xl header was screenshotted first and rejected: it reads as
  another headline, which is the problem being fixed.

Ratings table verdict column
- New .rating-cell block: a one-column 15rem grid, segmented group with
  clear/cleared flush right, note field beneath on the same width, group
  top-aligned with the article title. 13rem cannot hold the labels plus
  the wider "cleared" state, so rows wrapped and overlapped the Article
  column.
- Drop the dead CurrentRow::verdict field left over from removing the
  badge (clippy -D warnings).

Also: reader-page on world/behind so the text-wrap: balance polish item
covers those chapters.

Verified on the dev server at 127.0.0.1:3602 in light and dark, desktop
and 390 px: rating clicks toggle .active/aria-pressed with no navigation
and no console output; note text round-trips; cargo fmt, clippy
--all-targets -D warnings, cargo test (445 lib + integration) and
npm run css:check are clean. See docs/plans/briefs/ui-pass/handoff-rating.md.
