/* ==========================================================================
   THEATRE WHITEBOARD LAYOUT

   A responsive CSS Grid layout for NHS Theatre Team Briefing boards.

   KEY DESIGN DECISIONS:
   ----------------------
   1. Uses CSS Grid with 'fr' (fractional) units for automatic responsive scaling
   2. No media queries needed for the patient grid - it adapts to any screen width
   3. Checkbox state colors use specificity-aware selectors (no !important needed)
   4. Column proportions are defined once and apply to both header and rows

   COLUMN LAYOUT:
   --------------
   - Patient info columns (Name, Unit, Procedure): Larger share (2fr-2.2fr)
   - Checkbox columns: Equal small share (0.8fr)
   - Dropdown columns: Medium share (0.9fr-1.3fr)
   - Comments column: Largest share (4fr)

   CHECKBOX STATE HIERARCHY:
   -------------------------
   - .checkbox-blank: White/grey background (zebra striping on even positions)
   - .checkbox-tick: Green background (#007F3B)
   - .checkbox-cross: Red background (#DA291C)

   PATIENT GRID HEADER — Matching the Physical Whiteboard

   The physical NHS Theatre Team Briefing whiteboard has:
   - 3 info columns (Name, Unit, Procedure) with solid blue background
   - 16 checklist columns with alternating pale blue / stronger blue bands
   - Text labels rotated ~50 degrees, anchored at BOTTOM-LEFT of each column
   - A thick black horizontal line separates header from data rows
   - CRITICAL: Header columns must align EXACTLY with the patient data
     columns below, so each label sits directly above its data cell

   The background bands fill each grid cell exactly (no overflow/skew)
   so they line up perfectly with the data columns underneath.
   The text is rotated and anchored at the bottom-left corner of each cell.
