/**
 * BH Coastal — Design Tokens
 * ---------------------------
 * This file IMPLEMENTS docs/design-tokens-register.md (Tier 3,
 * canonical). That register is the source of truth — it separates
 * what's actually founder-approved (e.g. the palette/type direction)
 * from what's Claude's engineering interpretation of that direction
 * (e.g. the exact hex values and typefaces below). If this file and
 * the register ever disagree, the register wins and this file needs
 * correcting, not the reverse.
 *
 * Every color, type, spacing, and layout decision on the site should
 * trace back to a variable defined here — nothing hard-coded
 * downstream.
 *
 * Direction: understated, masculine coastal luxury. Timeless,
 * editorial, mature. Deliberately avoiding bright resort color,
 * gradients, glass effects, heavy shadows, and animation for its
 * own sake.
