/* --- Tooltips --------------------------------------------------------------
   Two forms, both dismissible on Escape without moving focus (see
   public/js/tooltip.js, which toggles [data-tooltip-suppressed] — WCAG
   2.1.4/1.4.13) and shown on both hover AND keyboard focus so mouse and
   keyboard users get the same information:

   1. `[data-tooltip="…"]` — a lightweight CSS-only bubble for a control that
      ALREADY has its own accessible name (an icon-only button's
      `aria-label`, a `role="img"` glyph's `aria-label`). Purely a *visual*
      affordance for sighted users; add it to the interactive/labelled
      element itself, never to a bare decorative span.
   2. `.tooltip-info` (+ `<x-tooltip>` Blade component) — a small "info"
      button for supplementary explanation that has no other on-screen
      representation (e.g. what a metric counts, why a threshold applies).
      Its text lives in a real DOM node (`.tooltip-bubble`) wired via
      `aria-describedby`, so screen readers announce it on focus regardless
      of visual hover state.

   Default placement is above the trigger; add `data-tooltip-pos="bottom"`
   for controls near the top edge of the viewport (e.g. the top bar) where
   an upward tooltip would clip. `data-tooltip-wrap` allows a longer,
   left-aligned, wrapped bubble instead of the default single-line one. */
