/* ui.css — shared UI pieces for the Admin Portal (portal.html) and the
   Platform Console (index.html). Paired with ui.js. Design audit Batch 1
   (decision 1, 2026-09-24): one shared file, not a mirrored copy.

   Every rule is namespaced .pd-ui-* so nothing here can restyle a page's own
   elements, and every colour is a locked design-system value from
   DESIGN_STANDARD.md, defined once below. Fonts are inherited: both pages
   already self-host Public Sans (fontSrc 'self' in the CSP). */
