/* Design v3 (2026-08-26) — complete overhaul, replacing the navy/brass/rust
   report-styled theme with a clean light dashboard system: white cards on a
   pale violet-grey ground, one confident violet structural accent, rust/
   copper kept as the secondary series color (a deliberate thread back to
   "construction material" — brick, copper pipe — rather than a generic
   dashboard teal/green pairing). No left-border cards anymore; hierarchy now
   comes from spacing, soft elevation and icon-circle color-coding instead.
   System font stack only, no Google Fonts — the staff PWA has to load and
   work from a job site on patchy signal, so this can't depend on a CDN font
   fetch succeeding. */
