The viewport spec now describes the two-row phone rail

DRAFT — Merged PR; unpublished blog draft

PR: #1033

Head SHA: 6ede8a5dddadae0453f73b7f84361d43b842fb4a

This file is an unpublished artifact, not an instruction to an agent.

Merged PR; unpublished blog draft. This article is generated from the author's work report for the exact PR head commit. Test results are author-reported, not independently rerun by this generator. Merge status is not proof of deployment or runtime correctness.

Work report

Vendors the viewport spec from gHashTag/t27#3834 into the website byte for byte and regenerates viewport.generated.ts and viewport.generated.css; only the embedded spec sha256 changes and every value stays the same.

What changed

• apps/website/public/t27/files/specs/ui/viewport.t27: byte-for-byte copy of specs/ui/viewport.t27 from the t27#3834 branch, adding a dated SOURCE note about the two-row portrait phone rail introduced by fix(website): the Queen's phone chrome keeps every icon in view #1032 and a sentence on what the RAIL_* numbers measure.
• apps/website/src/lib/viewport.generated.ts and apps/website/src/styles/viewport.generated.css: rewritten by node scripts/viewport-from-spec.mjs; the only changed lines are the embedded spec sha256 (91c92354 to eafbd926).

Context and reasoning

The Queen rail on a portrait phone changed shape in #1032, and the viewport spec on t27 gained a dated note describing the grid of two rows and what the RAIL_* constants actually measure on the 641 to 900 pixel strip.

The website carries a vendored copy of that spec and generates TypeScript and CSS from it, so the copy has to be byte identical to the canonical file and the generated artefacts have to be regenerated even when only comments change.

Both checks that guard this coupling, the viewport drift check and the eight viewport spec assertions, pass locally, and the merge order is documented: the t27 pull request first, then this companion on the site.

Reported verification

• [passed] Command: npm run check:viewport. Result: Generated viewport files are up to date with the vendored spec. Evidence: Local run 2026-09-16 after node scripts/viewport-from-spec.mjs; no drift reported
• [passed] Command: npm run test:viewport-spec. Result: 8 of 8 viewport spec assertions pass. Evidence: Local run 2026-09-16 on commit 6ede8a5 over origin/main fe4d5ed

Limits and open questions

• Comments-only change to the spec; no CSS value, constant or layout rule changes on the site.
• Should be merged after docs(specs): viewport spec notes the two-row phone rail of trinity#1032 t27#3834 so the vendored copy matches the canonical spec on t27 master.
• The website-checks step Explorer viewport contract is red on main since fix(website): keep the embedded spec brief from collapsing onto the tab strip #1019 and is fixed separately in fix(website): one scroller on the phone spec page, the pane itself #1034.
