/*
 * Be Vietnam Pro, self-hosted (SIL OFL 1.1, see OFL.txt). The subset is made by tools/fonts.
 * The file name carries the version, so `/fonts/*` is cached as immutable: change the glyph set or
 * this CSS and the name changes with it.
 *
 * `font-display: swap` shows text at once in the fallback face below, then swaps. The fallback
 * faces are local Arial (or its metric twin Liberation Sans), scaled to Be Vietnam Pro's average
 * advance width (Vietnamese sample text) and line box, so the swap barely moves the layout.
 *   size-adjust = BVP avg advance / Arial avg advance   (0.4797/0.4460, 0.4906/0.4767, 0.4960/0.4767)
 *   ascent-override  = BVP hhea ascent  (1.000 em) / size-adjust
 *   descent-override = BVP hhea descent (0.265 em) / size-adjust, line-gap-override 0 (BVP has none)
 * The font-family token (--font-sans) names 'Be Vietnam Pro' and 'Be Vietnam Pro Fallback'.
