/* R52 (Claude, 2026-10-22): the small extra pieces the Version 4 family / teacher / owner screens need (school messages, incidents, emergency
   contacts, consent ledger, AI policy, billing sandbox, gradebook, attendance, student support, parents, resources). Everything else is the
   Lab's own components (panel, btn, pill, tbl, list, ts-*), so Versions 3 and 4 style them already. Colours come from currentColor or are
   tinted with transparency, so they read on V3's dark glass and on V4's white glass; html[data-look=v4] gets a few navy/gold touches.
   Logical properties (inline-start / end) keep Arabic (dir=rtl) right. */
