/* =====================================================================
   RespMech — respmech.dk
   Design system. One file: tokens → base → layout → components → motion
   → responsive → reduced-motion → print.

   Brand bridge:
   • Old respmech.dk identity — azure #03A9F4 + orange #FF9800 over dark
     slate, Muli/Mulish type, a "graphs · code · calculations" texture.
   • New RespMech branding — the azure "signal-tile" logo and the desktop
     app's calm, light "scientific instrument" UI (steel-blue #2C6E9B,
     white cards on a soft neutral canvas).

   CSP note: no inline styles anywhere. All SVG in the HTML uses
   presentation attributes only; every animation lives here.
