/* Vendor landing pages styles (/cameras/<vendor>/ et al).
 *
 * Standalone stylesheet - vendor pages do NOT load the main app CSS bundle
 * (175KB with maplibre / chart / player styles) to keep first paint fast
 * on landing pages indexed by search engines. Brand tokens are duplicated
 * here from src/styles/tokens.css; when the design system changes, this
 * file needs a manual sync (low frequency, acceptable cost).
 *
 * Dark-mode default (per CLAUDE.md product convention). prefers-color-scheme
 * light override gives bone palette. No explicit toggle UI on vendor pages -
 * the user can switch theme on the main app, and we follow OS otherwise.
