   Global :focus-visible ring (audit Tier 1 #5, a11y WCAG 2.4.7)
   Many components set `outline: none` on :focus to avoid the default
   browser dotted ring (~25 sites across css/). The replacement was
   inconsistent — some components added border-color or box-shadow,
   others left focus invisible. Keyboard users couldn't tell which
   element was focused. This rule provides a single, brand-consistent
   amber focus ring on ANY focusable element navigated to by keyboard
   (Tab/Shift+Tab/arrow). It uses :focus-visible (not :focus) so mouse
   clicks don't paint the ring — preserving the design intent of
   suppressing :focus on click-driven interactions.

   Per-component overrides that set their own :focus-visible (e.g.
   .task-drawer__close, .task-drawer__doc-expand-summary) win via
   selector specificity — this is the universal fallback.

/* Suppress the visible ring on :focus when not :focus-visible
   (mouse / touch clicks). Browsers that don't support :focus-visible
   (very old) keep their default :focus ring — a degraded but
   acceptable fallback. */

/* ═══════════════════════════════════════════
   Mobile horizontal-overflow safety net (≤768px)
   - Each top-level view gets `overflow-x: hidden` so a child with an
     unbounded width can never push the whole viewport sideways. Vertical
     scroll continues to work via the existing per-view `overflow: auto`.
   - Long unbroken strings (URLs, file paths, code spans) inside content
     surfaces wrap instead of forcing horizontal scroll. `anywhere` is
     used over `break-word` because it also breaks inside long tokens
     (URLs without spaces, /path/to/file/like/this), which `break-word`
     leaves alone.
   - Components that intentionally use horizontal scroll (kanban scroll,
     log streams, code blocks, tab nav, server-top__table-wrap, the
     org-chart, etc.) opt out via `overflow-x: auto` set on their own
     wrapper — they remain unaffected because hidden on the parent only
     clips content that wasn't already in its own scrollable container.
