/* Nakshatra site. Tokens from projects/astro/DESIGN.md.
   Light theme = "Panchang Patra" (HEAD DESIGN.md): paper #F4EBDA, ink #1C1712 (15.0:1),
   almanac red #C23417 for labels and links (4.67:1 on paper, 4.87:1 on rail), deep marigold
   #8A5A12 for readable gold (5.0:1); marigold #E89B0C is 1.9:1 on paper, so marks and rules only.
   Dark theme = the shipped "Jantar Mantar Night" palette (DESIGN.md at 70c212e3): night #0D1230,
   surface #171D42, ivory #F1E8D2 (15.0:1), gold #D9A441 links (8.15:1), slate #8B98C2 (6.43:1).
   The Play screenshots show the shipped night UI in both themes (1 px frame).
   Fonts: Khand 600 (display) and Palanquin 400/600 (text), static weights, Latin subsets. */
