/* UiPreview — a pannable catalog of real UI "particles" (cal.com/oss-style), each rendered in
   the proofed font so it's a working specimen of the font in UI micro-typography. Ported from
   ReCal's coss.css; ReCal tokens are remapped onto font-proofer's theme tokens.

   WEIGHT MODEL: all text inherits --w-default (the default weight); elements marked .coss-b
   use --w-bold. Raising the default raises both. Optical sizing is auto so headings pick up
   the display cut and body the text cut. */

   remap of ReCal's four-step scale onto font-proofer's tokens is gone. Only --text-faint
   still needs a stand-in, since font-proofer has no fourth text step. Scoped to the board
   so nothing leaks out. */
