   DWR Event Calendar — Base styles
   ──────────────────────────────────────────────────────────────────
   Design tokens, sr-only utility, and the universal :focus-visible
   rule now live in dwr-shared/assets/css/dwr-frontend-theme.css.
   This file should be enqueued with 'dwr-frontend-theme' as a dep.

   What stays here:
   - calendar-specific aliases (--dwr-cal-* → --dwr-fe-*)
   - the shared modal styles (used by every calendar layout)
   - .dwr-cal-title / .dwr-cal-subtitle helpers
   - .dwr-sr-only fallback (ดูเหตุผลด้านล่าง)
   ─────────────────────────────────────────────────────────────────── */

/* ── .dwr-sr-only — fallback ในตัวเอง (DWO11-29) ──
   ตัวจริงอยู่ใน dwr-shared/dwr-frontend-theme.css แต่ถ้าเว็บไหน dwr-shared
   เก่า/ไม่ทำงาน/dep หลุด → ข้อความที่ตั้งใจให้ screen reader อ่านอย่างเดียวจะ
   "โผล่มาให้เห็น" เช่นปุ่มดูทั้งหมดกลายเป็น
   "ดูทั้งหมด (เปิดหน้ารวมกิจกรรมทั้งหมด)"
   กฎของฟลีต: CSS ปลั๊กอินต้องมีค่า fallback ในตัวเสมอ ห้ามพึ่ง dwr-shared อย่างเดียว
   (ค่าเท่ากับใน dwr-shared เป๊ะ — ถ้าโหลดทั้งคู่ผลลัพธ์เหมือนกัน ไม่ตีกัน) */
