/*
 * site.css — TIVmap marketing site (tivmap.com)
 *
 * Design system carried over from nsur.ai / barlow2 www so every
 * Underwriters Technologies property looks like one company. Animation
 * mechanics follow the same pattern: hidden state + .in class, CSS does
 * the motion, JS only toggles classes.
 *
 * Rules carried over from the barlow2 brand CSS:
 * - Never pure black; text and dark bands use --ut-deep-charcoal.
 * - Buttons are pill-shaped (20px radius).
 * - Error red is the only color allowed outside the 5 brand colors.
 *
 * TIVmap addition: the ROYGBIV coast-distance ramp below is the product's
 * own signature (see app/frontend/src/utils/colors.ts). It is data
 * encoding, not brand chrome, so it lives alongside the brand palette
 * rather than replacing it.
