  Moves bilingual copy out of app.js and catalog.js into typed Astro content
  collections without altering a string. Use for tasks 03-04 and any later
  content relocation. Do not use for markup or styling.

You own `src/content/` and `src/content/config.ts`, and you are their only
writer. Your job is a lossless move, not an edit.

**Read first**: `.agents/rules/content-i18n.md`. **Load skill**:
`content-migration`.

## What you are moving

~50 `{ en, pt }` keys from `app.js` (`phases`, `handsOnPrompts`, `modelGuide`,
`skillSources`, `skillInstallPrompts`), plus 24 review entries from `catalog.js`
and `submitted-catalog.js`.

These are hand-written translations with deliberate tone. **Copy them
mechanically. Never retype.** Retyping introduces drift nobody notices until a
Portuguese speaker does.

## Procedure

Extract → write into collection → diff extracted-before against extracted-after
→ only then delete the source. If the diff is not empty, you changed content.
Fix it before continuing.

Both locales required in the schema. A missing `pt` must be a **build error**,
never a silent English fallback — that is how bilingual sites quietly become
monolingual.

## The trap that will catch you

`skill-reviews/improved/**/SKILL.md` is generated from `catalog.js` by
`scripts/build-skill-review.mjs` and the output is **committed**. Move
`catalog.js` and the generator keeps running against nothing — silently. Either
re-point it or replace it, and update `package.json`, `README.md`,
`docs/operations-guide.md`, and the review desk footer, all of which reference
it.

Also: the review desk's diff view compares original and improved **source
text**. If you convert `improved` to rendered Markdown, keep the raw string
available or the diff view breaks.

## The language-switching decision

Client-side swap (matches today, no URL change — recommended) vs route-based
`/en/` `/pt/` (better SEO, changes every URL, needs redirects). Surface it, get
a decision, record it. Either way `<html lang>` tracks the active language.

## Done when

The string diff is empty, both locales validate, the generator still produces
identical output, and `pnpm run verify` is green.
