/* =============================================================================
   YKSA UI kit. Ships with yksa-web-kit; see ecosystem/ui-kit.md.

   Requires Bootstrap >= 5.3: the state pills below are built on the
   --bs-*-bg-subtle / --bs-*-text-emphasis / --bs-*-border-subtle families, and
   text-body-secondary is a 5.3 utility. On 5.2.3 every rule here still parses
   and the page renders wrong -- muted text is not muted, tinted backgrounds are
   transparent. The bundled bootstrap.min.css is the version this is written for;
   do not point a service at its own older copy.

   Two rules govern the whole kit:
   1. Typography carries meaning through weight, colour and size only. No
      small-caps, no thin/semibold, no letter-spacing, no .display-*. Weights
      are 400 and 700.
   2. Colour is never the only signal. Every state renders an icon and a word
      alongside its hue.

   Anything Bootstrap already provides is used as-is. The classes below exist
   only where it has no equivalent.

	   so everything here stays below that.
