/* TASK-730 (D223) shared primitives, lifted from the d215 artboard's product
   CSS (docs/design/artboards/d215/index.html, `.app` block). Class names carry
   a v2p- prefix so they cannot collide with the existing v2 chip, dot, pane and
   button rules. Colours and shape come only from the --v2-* tokens in v2.css;
   the artboard's short names map as: --sf surface, --t surface-tint, --d
   border-soft, --b border, --mu text-muted, --se text-secondary, --ph
   text-placeholder, --ink text-primary, --ink2 ink-2, --g page-bg, --c accent.
   Pinned by __tests__/v2Primitives.test.tsx.

   Adopting a primitive (#3154): a `.v2-root button.<class>` rule in v2.css
   (0,2,1) outranks every one-class v2p- rule (0,1,0), so adding the class is not
   enough. Delete the element's bespoke look (size, border, fill, radius, colour,
   hover, focus) and keep only layout and states the primitive lacks: :disabled
   (no primitive has one) and a focus ring wherever a later rule sets
   box-shadow. */
