/* Parcelscan design system — ElectroFleet branding.
 *
 * Tokens are taken from the live LocationPlanner frontend
 * (Prod/locationplanner/Frontend/styles/base.css + theme.css) so both products
 * look like one company. The brand teal #62c1b3 is the value in the official
 * logo.svg, corroborated by the "ElectroFleet" colour scheme in
 * Consulting_Pipeline/Templates/Slide_Master_EF.pptx.
 *
 * Two deliberate additions on top of what LocationPlanner has:
 *   1. Inter is actually loaded. The corporate slide master names it as the
 *      heading font, but no project in the tree ever linked a webfont, so every
 *      app silently fell back to the system stack.
 *   2. Semantic tokens (--success/--warning/--danger) exist. LocationPlanner
 *      hardcodes these per component and has drifted into a mix of its own muted
 *      set and leaked Tailwind reds.
