/* ── Phones: the resting (un-portaled) bubble must not lay out past the viewport ──
   The CSS-only bubble is centred on its icon (left:50% + translateX(-50%)). On a narrow
   screen any hint sitting near the right edge — e.g. #info-hint-arena-fair-join — extends
   past the viewport, where the shell's html{overflow-x:clip} clips it: unreachable, and it
   registers as page-level horizontal overflow. Pin it to the viewport gutters instead.
   js/info_hint.js still owns real placement (it portals the bubble to <body> and adds
   .info-hint-bubble--portal), so this governs only the resting / no-JS state.

   MEASURED: this only half-works on its own. `position:fixed` resolves against the nearest
   ancestor with backdrop-filter/transform (the CSS containing-block rule this file already
   warns about above), so on /technical/ the bubble lands at left:29..346 — inside the blurred
   .chart-card, not the viewport — and inside a translated carousel slide (value.html) it lands
   at left:-129, off the screen entirely. It is therefore kept only as the no-JS fallback
   (best effort). Whenever js/info_hint.js is live — html.info-hint-js, i.e. always in practice
   — the resting bubble is instead collapsed to an sr-only 1x1 box: it cannot overflow from any
   containing block, it stays in the a11y tree for aria-describedby, and the only bubble a
   phone ever shows is the portaled one, which <body> hosts and the script clamps. */
