   focus management on view change, hover gated to fine pointers, ≥ 44px
   touch targets, reduced-motion honoured). This section adds:
     1. A globally visible `:focus-visible` ring (Bootstrap strips outlines
        on .btn / .btn-link — re-instate without using `!important`).
     2. A skip link that jumps to the message log (first focusable element
        in <body> per WCAG 2.4.1 Bypass Blocks).
   Light theme only. Logical properties only. No new deps.
   Bootstrap's `.visually-hidden` already loaded — not redefined here.
