/**
 * Horizon Theme — "Clean Editorial" base skin
 *
 * Pure white surfaces, near-black text, deep teal accent. Designed for
 * photographers, writers, designers, and minimalist creators who want
 * a high-contrast, magazine-clean look. All-Inter typography (sans-serif
 * for crisp editorial rhythm); zero-radius corners; featherlight shadows.
 * The per-tenant brand_primary override still layers on top.
 *
 * Contrast audit: all key pairings pass WCAG 2.1 AA.
