/* ---------------------------------------------------------------
   Prescription manager — chamber UI

   Density over decoration. A consultant sees forty patients an evening
   and the screen has one job: get from a name to a printed pad without
   the mouse. Colour is used only where it carries meaning: the
   apothecary green of a pharmacy sign for anything that commits, the
   maroon of a printed letterhead for the Rx sigil and for deletions.
