   control that names its own size in a class rule still wins here and composes
   the same floor itself via max() — this rule exists so the fields that simply
   inherit (`font: inherit` above) are covered too, without a class having to
   opt in. `1em` is the inherited size, so on a precise pointer the floor is 0
   and this resolves to exactly what the element rendered before.

/* ── FOCUS CONTAINERS NEVER RING ────────────────────────────────────────────
   A focus ring belongs on a control the user REACHED — i.e. something they can
   tab to. An element that is focusable only so script can move focus INTO it —
   a <dialog>, or any tabindex="-1" container — is by definition not
   keyboard-reachable, so a ring around it is always a bug: the user gets a box
   they never asked for, around a whole panel, that no keypress explains.

   This is the SOURCE fix for a bug the app had been patching one component at a
   time (.sheet:focus, .modal__close:focus/-visible, …): opening a surface moves
   focus inside it, the UA decides that focus should be visible, and a ring
   appears the instant the panel opens (reported on the mobile Rail's close icon,
   2026-07-23).

   Keyboard-reachable controls are deliberately untouched — they keep the
   :focus-visible ring above, which is the WCAG 2.4.7 (Focus Visible)
   requirement. Element+attribute specificity (0,1,1 / 0,2,0) beats the
   :focus-visible rule above, so order here is not load-bearing. */

   has attribute-selector specificity (0,1,0) and is clobbered by any
   class-selector display rule (e.g. .copy-field { display: flex }).
   Marking the rule !important here ensures the HTML semantic always works
   so the field-reveal pattern (and every other Stimulus reveal/hide)
