/* POS-LESSONS-001 — Lessons Calendar (month view + filters + create/edit modal).
   Self-contained (own class names, no reliance on session-calendar.css's
   .month-grid/.month-cell — that stylesheet's colors are undefined CSS custom
   properties in this app, since office-compat.css (which defines them) is
   never loaded here; those rules are otherwise-unused leftovers). Colors below
   match pos.css's own dark-theme palette (--primary, --border, --dark, --light
   are POS's actual :root tokens). */
