/* =====================================================================
 * dr-lesson-base.css
 * Darja Rihla — GEDEELDE basis-laag voor ALLE Nederlandse lessen (1 t/m 8)
 * ---------------------------------------------------------------------
 * Doel: één plek voor de premium-chrome die elke les deelt:
 *   • Nederlandse vlag + oranje brand-accent (op ALLE lessen, nu zichtbaar)
 *   • Uitschuif-TOC links (slide-out sidebar, zoals andere darjarihla-posts)
 *   • Scroll-progressbar bovenaan
 *   • Canonieke width-fix helpers (GOV-005/006)
 *   • Kleur-variabele CONTRACT dat elke les invult (--les-accent etc.)
 *
 * Geladen op les 1-8 via functions.php (dr_is_any_lesson_singular), VÓÓR
 * de per-les CSS, zodat een les altijd kan overschrijven.
 *
 * Bestaande lessen worden NIET gebroken: de vlag/oranje + TOC haken aan op
 * de huidige .dr-lesN-nav / section[id] markup. Volledige theming volgt bij
 * de per-les conversie.
