/* ─────────────────────────────────────────────────────────────────────────────
   IVALDI — a dusty tome.

   Every other tool in the suite is dark: a terminal, an instrument, a night
   sky. This one is a book. It keeps the suite's structure — the same nav, the
   same panel rhythm, the same monospaced labels — and inverts its material.
   Vellum instead of void, sepia ink instead of cyan, gold leaf instead of glow.

   The colour system rests on one rule that took some care: on a dark page,
   "important" means brighter, and every accent can be a light. On vellum it
   cannot — brighter than parchment is white, and white is a hole in the paper.
   So emphasis here is carried by *warmth and depth* rather than by luminance.
   Gilt (a saturated warm ochre) advances; tarnish (a desaturated cool slate)
   recedes; and the ink between them does the reading.
