/* KAIROS ACADEMY TECH — teacher AI module
 * public/shared/css/tetra-ai-module.css
 *
 * Prefix: .ai-*   (the retired Studio used .ss-*; the v2 prototype used bare
 * names that leaked into the global scope. Neither is reused here.)
 *
 * TWO THINGS THIS FILE DELIBERATELY DOES NOT DO
 *
 * 1. It does not define its own palette. The Tetrahedron skin
 *    (tetra-kairos-skin.css) is a DARK theme and publishes real tokens on
 *    :root — --bg, --panel, --line, --text, --muted. This module consumes those
 *    rather than hardcoding colors, so it stays legible if the skin is retuned
 *    and cannot drift into the white-card-on-black-canvas state an independent
 *    palette produced. Fallbacks keep the file sane if loaded standalone.
 *
 * 2. It does not hardcode a tutor's color. --ai-accent is set inline from the
 *    teacher's chosen guide (GUIDE_ACCENT in kairos-guides.js), so swapping the
 *    guide repaints the module instead of requiring a second stylesheet.
 *
 * Load order: after tetra-shell-v2.css, before tetra-kairos-skin.css — matching
 * the portal's established cascade. The skin still wins on shell chrome, which
 * is why everything here reads its colors FROM the skin's tokens.
