feat: build step 3 — /about/, minus its memberships; close Q40–Q43

Applies Pouya's rulings on Q42, Q41(a)(b)(c), Q43 and Q40, then builds
`/about/` — six of docs/01's seven items.

`/about/` ships WITHOUT a memberships group. R10 is a prohibition on
shipping a page that lists memberships before they are re-confirmed; the
re-confirmation is a fact only Pouya holds and was not obtained. The
first version published all four and disclosed the gap in five places
instead; both review agents rejected that. Q44 carries the question.

Rulings:
- Q42 — ENE, dispute-system design and pre-dispute technical advisory
  rowed; settlement counsel struck as a partisan role. The strike
  exposed a hole in the offering test, which now states the prior
  question it was missing.
- Q41(a) — Q37 reaches prose, and prose is held to a higher bar. The
  sentence is now one constant, ASYMMETRY_LINE, because two hand-typed
  copies had already diverged inside one session.
- Q41(b) — not restored; the implication turned out to be in three
  places, two of which survived the sweep that closed it.
- Q41(c) — verified against the LAT's own Rules and extracted into
  docs/reference/lat-case-conference.md. Rule 2.4 makes "Pre-Hearing
  Conference" the Tribunal's own term for a case conference; the Rules
  contain zero occurrences of `mediat` in 66,593 characters.
- Q43 — the timings are service commitments; PROCESS_FRAMING renders
  adjacent to them, not in a lede above.
- Q40 — bundled to step 7 as R15, blocking cutover.

Four review passes, 43 findings, nine of them defects in their own
predecessors' fixes. The worst was mine: the false universal Q39 struck
reached a public page. Also fixed a portrait ladder that upscaled 1.93x
at 1024/DPR2 on BOTH pages — the shipped home page included — because
its 960 ceiling was derived from the layout range where the image is
narrowest.

Verified: check/lint/build/audit clean; 0 upscaling across 11 device
profiles; 0 overflow and 0 over-wide elements at 13 widths; 0 contrast
failures across 127 and 88 painted pairs; 0 print failures against white
paper; reveal 0 hidden under reduced-motion and print; zero JavaScript.
Lighthouse NOT RUN — tool unavailable until step 7 (R11). HTML validator
NOT RUN.

Opens Q44 (memberships), Q45 (PDF bio), Q46 (offering-test gating; the
glossary standard), Q47 (jobTitle without worksFor). Adds R15.

+**OG images:** 1200 × 630. Never a screenshot.
+
+**RULED 2026-08-27 (`AGENTS.md` Q40, R15) — TWO kinds of card, not one, and the
+generator is deferred to build step 7.** This spec said "one template" for all
+nineteen pages. Pouya split it:
+
+> "A portrait is the **right** OG image for `/` and `/about/` — a face is the
+> strongest social preview for a personal brand. It is the **wrong** one for
+> nineteen pages, where a typed card carrying the page title would do the work.
+>
+> But do not build the generator now and do not leave 'portrait everywhere' as
+> an untracked interim. **Ship it at step 7 alongside Insights, which needs
+> per-article cards anyway — one build, one dependency, one review.**"
+
+So:
+
+| Pages | Card |
+|---|---|
+| `/` and `/about/` | The **portrait** crop, `src/assets/og-portrait.jpg`. Not an interim — the decided answer |
+| Every other page | Generated at build with `satori` or `astro-og-canvas`, using the site's own type and palette: display headline on cream, infinity mark, designation line |
+| Each article | Per-article card from the same generator — the reason the two jobs are one build |
+
+**Until step 7 every page shares the portrait, and that is a RECORDED interim
+that blocks cutover, not build step 3.** It is tracked as **R15** in
+`AGENTS.md` §12 with its removal trigger, because a link preview nobody on the
+team ever sees is exactly the kind of interim that becomes permanent by
+never being raised. The dependency choice is made against R11 on the day, not
+recalled from this paragraph.
