/* Etap M3 (FR-USR-005/006, WCAG AA):
   - Relative units throughout (rem/%/em), no fixed px widths, so the page reflows
     cleanly at 200% browser zoom without horizontal scrolling (WCAG 1.4.4/1.4.10).
   - Text color #1a1a1a on #ffffff and link color #0b4fa8 on #ffffff both exceed the
     4.5:1 minimum contrast ratio for normal text (WCAG 1.4.3).
   - :focus-visible is always drawn, never suppressed (WCAG 2.4.7) — every interactive
     element (links, buttons, form fields) gets the same visible outline.
   - No animation/motion, no color-only status indicators (status text always carries a
     plain-language label, never color alone — see Pages/Instrument/View.cshtml). */
