/**
 * AI Tools Styles
 *
 * Phase 1: Loaded ONLY on the homepage (is_front_page() branch in
 * inc/assets.php). Contains styles for the AI Assistants section (S4)
 * and shared AI tool card treatment.
 *
 * Phase 2 extension: Also load on hz_ai_tool archive and singles
 * (add conditional branch in inc/assets.php). CSS in this file must
 * work correctly in both contexts.
 *
 * Background: Dark Forest Green (#0A3329) — deliberately distinct from
 * standard Forest Green (#0F4C3A, --color-primary) to visually separate
 * the AI section from standard brand sections. Not in design token set —
 * defined locally as a section-level value.
 *
 * Uses design tokens from tokens.css. Gold (#D9A441, --color-accent)
 * is the AI signature colour; used on ✦ characters, WAITLIST badges,
 * and AI disclosure text — never as text on white (contrast failure).
 *
