/* =============================================================================
   WESTORABLY
   -----------------------------------------------------------------------------
   Reference points: a trade catalogue, a facility floor plan, an invoice.
   Not a SaaS template.

   Rules this file follows, deliberately:
   1. Structure comes from hairline rules and a visible column grid, never from
      floating cards with soft shadows.
   2. No box-shadow anywhere. No gradients on buttons. No blurred colour blobs.
   3. Corner radius is 0 or 2px. Nothing is a pill.
   4. Icons sit inline with text at reading size. They never live inside a
      tinted rounded square.
   5. Motion is limited to things that carry meaning: a rule drawing itself,
      a number counting, a unit map filling, a keypad entering a PIN.
   6. Type: Newsreader (editorial serif) for headings, Public Sans (a civic
      typeface built for utility text) for everything read, Roboto Mono for
      anything numeric so figures line up in columns.
