/**
 * Motorwise Tool Pages — Vehicle Report scaffold chrome
 *
 * Shared styling for static tool pages rebuilt onto the new design direction
 * (see docs/tools-overhaul/MPG-RECIPE.md): a single page of white section cards
 * on a #ECEEF1 ground, restrained iconography, single brand-blue accent.
 *
 * Nav model (per recipe): a mobile-only bottom nav toggles the page's tab
 * panels (e.g. Checker | Guide); on desktop every panel is shown in one scroll.
 * Most styling is via Tailwind CDN utilities; this file holds what they can't.
