- Wrapped the static English prose in `data-language-content="en"`
- Paired every english prose with its Portuguese counterpart in `data-language-content="pt"`
- Updated static `Localized` props in Astro blocks
- Regenerated the static snapshot because Attempt 2 of the migration dropped several legacy sections (`.builder-intro`, `.exercise-brief`, `.comparison-strip`, etc.) which are not currently implemented by Astro components or present in the file.
Capture rendered-text and visual baselines before route migration, and detect external CSS dependencies. Do not change verify.mjs assertions; task 02 must remove the known legacy font URL before the audit can pass.
