Render the pages from a string catalog and add a Spanish edition

[ChelseaKR]

What

The three pages are English only, with every sentence inline in render.py, and the README conformance table records Internationalization as applies, not met. This moves every string the pages print on their own account into a declared, ordered English catalog, makes render.py take a catalog parameter, and adds site/es/ rendered from a Spanish catalog over the same artifacts: same numbers, same tenths, same table order, same markers, same three-state key. Quoted publisher text stays in the publisher's language and is labeled as a quotation. A catalog missing a key or a placeholder is refused at build time; the Spanish catalog is published only once reviewed by somebody who reads Spanish, and until then the build can produce it locally while the workflow withholds it.

Why it matters

This is civic data for California readers and the pages are the product. The sibling wildfire-service-territory-overlap did the extraction half under its ADR 0016 and proved a second edition cannot change a figure; perimeter should hold to the same rule, and the pages add what the sibling lacks: a rendered UI where layout, lang attributes, and reflow at 320 pixels must hold in both editions. Numbers keep a hard-coded decimal point deliberately, so one artifact writes every figure one way.

Scope

• src/perimeter/catalog.py with the English catalog; render.py free of prose (a test parses the module and refuses a readable string).
• site/es/index.html, perimeters.html, dins.html with lang="es", cross-links between editions, and the same WCAG, reflow, contrast, and prose-number gates over both.
• docs/I18N.md declaration and an ADR; a test rendering both editions and asserting every figure and interval string identical.
• A reviewer-attestation field in the Spanish catalog that must be set before pages.yml publishes it.

Out of scope

• Localized number formatting.
• Translating publisher quotations or docs/MARKERS.md.

Done when

• Both editions build offline from fixtures, pass every page gate, and differ only in prose.
• A Spanish catalog missing one key fails the build naming the key.
• With the attestation unset, make pages builds site/es/ and the publish workflow skips it, stating why.

Pointers

• src/perimeter/render.py, tests/test_pages_html.py (prose-number tracing), .github/workflows/pages.yml
• wildfire-service-territory-overlap: src/wildfire_service_territory_overlap/catalog.py, docs/adr/0016-the-report-words-live-in-a-reviewed-catalog.md, its issue The audit said six fields publish recorded zeros and five do #55

Triage against origin/main @ d4f533f (2026-09-06). Not built: no src/perimeter/catalog.py, no site/es/, every string still inline in render.py.

Split verdict, and the split is exactly where the issue puts it.

Automatable: the extraction half. Move every string the pages print on their own account into a declared, ordered English catalog, make render.py take a catalog parameter, add the test that parses the module and refuses a readable string, and add the test that renders two editions and asserts every figure and interval string is byte-identical between them. That is mechanical, it is testable offline, and it is worth doing on its own — the sibling project did the same half under its ADR 0016 and proved a second edition cannot change a figure.

Not automatable: publishing the Spanish edition. The issue is explicit — "the Spanish catalog is published only once reviewed by somebody who reads Spanish" — and asks for a reviewer-attestation field that must be set before pages.yml publishes it. An agent producing the Spanish strings and setting the attestation would be attesting to its own work, which makes the gate decorative. This is civic data for California readers; a mistranslated marker or three-state key label is worse than an English-only page.

Recommended order: land the extraction with the attestation unset, so make pages builds site/es/ locally and the publish workflow skips it stating why. Then the only thing outstanding is a person who reads Spanish, which is a much smaller ask than a whole feature.

Needs from the owner: a Spanish reviewer, and their attestation.
