/* ============================================================================
   Shared look of the three panels (Master, Staff, Institute) — shared/ui.php
   ----------------------------------------------------------------------------
   1. Colours and sizes          4. Top bar, side menu, content (every panel page)
   2. Sign-in page               5. Dashboard
   3. Small parts (icons)        6. Support tickets
                                 7. Movement (off when the visitor asks for less)
   Each panel sets --accent and --accent-2 (ui_colours()). Parts 4–6 are for the
   screen only, so printing marksheets, certificates and lists never changes.

/* ---------- 4b. Boxes and drop-downs of the old pages (every panel page) ----------
   The old Materialize boxes were only a thin grey line under the text, so a box was hard to see, and
   the old select2.min.css made every drop-down 420 px wide: in a narrower column it ran over the box
   or button beside it. Here every box and drop-down has its own outline, a filled box shows its name
   in the outline's top edge, and a drop-down keeps to its column. Heights stay as they were (the
   one-screen forms of 6d set their own), so every form still fits where it did. */

   small laptop, roomier on a big monitor. Tablets: two fields a row; phones: one. */
