/* Sajana Tech — company site.
 *
 * Navy / white / gold, the same palette Gurukul AI uses (rules.md,
 * "Appearance"), because the product is the company's most visible face and a
 * parent site in unrelated colours reads as a different organisation.
 *
 * Every colour is a token, and each is chosen against the surface it sits on:
 * body text needs 4.5:1, large text 3:1. Gold is a FILL that takes dark ink —
 * gold text on white is 2.1:1 and unreadable, which is why `--gold-ink` exists
 * separately.
