   Midnight glass and liquid gold. The identity is the old one (ink, royal
   navy, royal gold, parchment; Libre Caslon for headlines); the material is
   new: frosted glass that catches the light, gold that moves like liquid
   metal, shapes that merge like liquid (inspired by Libraries.dev, written
   here from scratch: no framework, nothing loaded from another site).
   Logical properties throughout, so Farsi mirrors without extra rules.
