/**
 * Angle Dojo - Martial Arts Dojo Theme
 *
 * Step into the dojo to master angles, protractors and lines. Deep indigo
 * night skies and charcoal mats set the scene, with belt-colored accents,
 * warm tatami tan panels, and a crimson sensei accent.
 * Builds on top of kid-friendly-theme.css
 *
 * Color Palette:
 * - Deep Indigo: #312E81 (page background, dojo night sky, titles)
 * - Charcoal: #1F2233 (cards, mats, deep shadows)
 * - Tatami Tan: #D9C7A3 (panels, figure backgrounds, soft highlights)
 * - Belt Gold: #E8B84B (arcs, progress, accents, brown-belt trim)
 * - Crimson Sensei: #D64541 (vertex dots, hard belt, error states)
