/* WAVVAW — customer portal design system
   ---------------------------------------------------------------------------
   Order: fonts → tokens → base → shell → components → pages → responsive.
   Identity: brushed steel and copper, from the logo. Copper is the action
   colour; steel greys carry the interface; green, amber and red mean status
   and nothing else.
   Rules: logical properties only (RTL is a first-class direction), no
   decorative gradients, motion only where it explains a change of state.
   The CSP forbids inline style attributes: every visual lives here. */
