/* ==========================================================================
   GCM provider portal — the only stylesheet.

   ★ NO WEB FONTS, NO CDN, NO @import. `style-src 'self'` in the CSP means an
     external stylesheet or font would simply fail to load, and a form that
     renders unstyled on a doctor's office PC because a third party was slow is
     a form somebody gives up on. System fonts render instantly and everywhere.

   ★ NO :hover-ONLY AFFORDANCES AND NO COLOUR-ONLY STATE. Errors carry the word
     "Error:" in text (see views/fields.ts); this file adds the red border and
     the left bar as REINFORCEMENT, never as the signal.

   ★ 44px MINIMUM TARGETS on every control and button. A lot of this gets
     filled in on a tablet, one-handed, next to a patient.

   Accessibility targets held here: contrast at or above WCAG AA on every
   text/background pair, a visible focus ring that is never removed, and a
   layout that reflows to 320px without horizontal scrolling.
   ========================================================================== */
