/*
 * BoardGameDrop design tokens: "Tile Drop" (owner decision, 25 September 2026).
 *
 * Board Navy ink on a warm paper page, white cards, cool grey hairlines and
 * one accent: Drop Coral, the colour of the tile that tips out of the grid.
 * Coral marks what moved (a price drop, a deal, the lowest point of a chart)
 * and nothing else. Archivo, set expanded and heavy, carries titles and prices;
 * Inter does all other work. Geometry is a quarter-rounded tile, and the one
 * tilted element on a screen is always coral and always at 15 degrees.
 *
 * Components read these custom properties only. The @font-face rules belong
 * in the site's base template so font URLs carry content hashes.

/* Metric-matched fallbacks, measured against the self-hosted files
   (scripts/build-site-fonts.py): size-adjust matches the average advance width of running
   text, the overrides match the real ascent and descent (hhea, 1000 upm).
   Archivo has two: its text cut (400, normal width) against Arial, and the
   wide headline cut (800 at font-stretch 112%) against Arial Bold, chosen by
   font-stretch so the wide titles do not borrow the text metrics. */
