/**
 * Uno LMS — design tokens (Phase 1: course-player surface).
 *
 * These :root defaults guarantee every uno-lms/course-player* block resolves
 * its tokens under classic themes (no theme.json) and provide literal hex
 * fallbacks for block themes whose theme.json does not define the equivalent
 * --wp--preset--color--* presets.
 *
 * Block themes that DO define matching presets override these values via the
 * wp_theme_json_data_default filter (Uno_LMS_Design_Tokens) at the default
 * layer; theme + user layers override on top of that.
 *
 * Token vocabulary is documented in docs/DESIGN-GUARDRAILS.md
 * § "Public token surface (Phase 1: course-player)".
