/* ── Tinted ── (a chip, badge or label in a colour the user picked: a
   workspace's, a folder's, a tag's, a kanban column's). The colour is the
   user's, so it never tells what kind of object a chip is: the kind is its
   mark (ChipMark), and a chip of an entity (a profile, a proxy, a password,
   a domain…) sets no `--chip` and stays neutral (kit kind-chip,
   2026-10-17). One rule for all of them: the element has the class and
   sets the colour with `style:--chip={colour}`. The whole chip takes it, as
   the kit's `.vd-kind-chip--color` does: the tint under it (--chip-tint),
   its border (--chip-edge, over transparent), its text the colour mixed
   towards --text (--chip-ink), so a pale colour on the light theme and a
   dark one on the dark theme still read (WCAG AA, chip-contrast.test.ts).
   `.active` (a picked one): the stronger tint (--chip-tint-strong), the
   border and a ring in the ink (currentColor) — the raw colour can vanish
   on the surface, the ink cannot; the selector outranks the colour-mix
   border below, so it holds with and without color-mix. No `--chip` → the
   neutral chip. `.tinted-text` is the text alone, for a coloured name with
   no chip around it. Shape (padding, radius, border width) stays the
   component's; the colours are this rule's alone — a component sets none
   on these elements, and a × or a secondary text inside one inherits the
   ink and fades by opacity (--chip-fade), never a fixed --text-* that
   does not follow the tint. A dot, stripe or icon with no text keeps the
   raw colour. Without color-mix (an old WebView) the chip is neutral with
   a border of the raw colour. */

   ligature joins characters, in the mono face (JetBrains Mono's code
   ligatures, its `calt`: != as ≠, -> as an arrow, >= as ≥) or any other;
   `font-variant-ligatures: none` turns `calt` off too, in WebKitGTK as in
   Chromium. The same holds for `.mono-chip` and code elements; a component
   sets no ligature rules of its own. Important: a utility, it holds against
   a component's `font: inherit` (which resets both). */
