/* ===================================================================
   dropbox.css — 📬 Homework Drop Box (pairs with dropbox.js).
   Notes-engine module: a compact, quiet card stack that sits INSIDE
   a note section — no page chrome. All selectors hwd- prefixed; loads
   after notes.css and leans on its variables (same deal as rps.css).
   Primary touch targets stay ≥44px; the register table collapses to
   stacked rows on small screens.
