   Barrio — Resident Portal
   Self-contained, framework-free stylesheet. Replaces Pico.css entirely.
   No external assets, no @import, no runtime network requests (CSP-safe).

   Structure:
     1. Design tokens (light + dark, prefers-color-scheme + [data-theme])
     2. Base / reset / typography
     3. Layout: shell, header, nav, container
     4. Components: flash, cards, buttons, tables, pills, forms,
        segmented control, definition rows, chat, timeline, slot grid
     5. States: focus, loading (.htmx-request), skeletons
