/* Layout: a phone-first ward handbook.  Teal app bar and bottom tabs; each topic carries a coloured index tile,
   like the thumb index of a pocket handbook; protocols read as flowchart boxes joined by arrows.  From 1000px wide
   the bottom tabs move into the bar and a guideline index sits on the left. */
