 * css/settings.css · The Long Game — Settings overlay + onboarding component styles
 * Purpose: visual styles for settings.js components that are NOT already in styles.css:
 *   .settings-body, .settings-pace-desc, .settings-about-copy,
 *   .accent-swatch-row, .accent-swatch, .accent-swatch-dot, .accent-swatch-label,
 *   .pace-opts, .pace-opt, .pace-opt-label, .pace-opt-desc,
 *   .onboarding-hint, .onboarding-name-field
 * Note: .overlay, .overlay-header, .overlay-back, .overlay-title, .overlay-body,
 *       .settings-section-title, .data-row, .data-row-*, .theme-opts, .theme-opt,
 *       .surface-card, .surface-card--*, .btn, .form-label, .text-input,
 *       .onboarding-panel, .onboarding-card, .onboarding-*, .action-sheet-*
 *       are all defined in css/styles.css — do NOT re-declare them here.
 * Related: js/settings.js (renders these classes), css/styles.css (base system),
 *          index.html (must link this stylesheet with the current ?v=N)
