/*
 * css/help.css · The Long Game — "How it works" overlay (v21)
 * Purpose: the calm accordion that teaches the app. Reuses the full-screen .overlay
 *   shell (css/styles.css); this styles the intro, the tiered section list, the
 *   expandable items, and the "More, when you're curious" reveal. One section open at
 *   a time (gentle pacing). References tokens from css/styles.css.
 * Related: js/app.js (openHelp), js/help.js (helpSections, HELP_INTRO)
