/* CheddaStack v1 design tokens: the shelf tag, in Chedda yellow (STK laws 32 and 44; ledger 23). Picked by Mark on
   2026-10-16 from three directions: direction B's type and shelf-tag cards, Chedda yellow as CheddaStack's own color,
   saved green where B had a sale red. The names are fixed; the site and the app use only these.

   The shelf-tag card, the one signature device: a white card with a 1.5px --line border and a 6px --cheddar band across
   the top (with a --hairline of --cheddar-edge under it), the price set big in the display face, and a small --cheddar
   tab at the top right naming what the card is, edged in --cheddar-edge.

   Edges (STK law 45): every button, chip, tab and badge carries a --hairline border one shade darker than its own fill
   (--cheddar-edge on yellow, --saved-edge on green, --live-edge on blue, --warn-edge on amber, --ink-edge on white), so
   the edges pop. The art is Eye Formation (theme/art.mjs): seeded SVG, no script. */
