Phase 4: Spanish and accessibility (draft, needs owner look)

Spanish

• Mobile menu button announced as "Abrir menú" / "Cerrar menú" (was English on every page).
• Blog index title, "Todos" tab, filter label and empty state follow the site language. All posts stay listed by default so Spanish readers can still open English guides.
• FAQ: "job programado" is now "tarea programada".

Accessibility (axe-core 4, WCAG 2.2 AA, 390px light mode): 2 issue types on every page before, 0 on 14 pages in EN and ES after.

• Contrast: light-mode slate-500 small text was 4.47:1 (needs 4.5). Now #5e7088, 4.75:1, visually almost identical. Dark mode unchanged. Ad labels and one About footnote moved from 2.46:1 to slate-600.
• Label in name: EN/ES buttons now announced "EN, Switch to English" / "ES, Cambiar a español". Browser tests updated to the new names.

Housekeeping

• PRs Phase 3 s2: one clock, simpler footer #184 to Medication guide: TL;DR first #187 also committed build-regenerated public/ files by mistake. Production was not affected (every deploy regenerates them). This PR adds a rule to CLAUDE.md and DECISIONS.md and commits none.

Checks

• Full npm test passes after a prerendered build. Entry bundle 62.00 KB gzip (budget 62.25).
• Not audited: dark-mode contrast, screen-reader walkthroughs, physical devices.
