/* Divya Darshan 360 — Ganesh Utsav route planner.
 *
 * Design brief: a navigation interface first, not a festival poster. It gets
 * used one-handed, outdoors, in direct sun, by people of every age, while
 * moving through a crowd. So: high contrast, large targets, warm neutral
 * surfaces that survive both daylight and night, and no decoration that does
 * not earn its place.
 *
 * Colour rules that matter:
 *   --brand (#F7AD3C) is an ACCENT only. It fails contrast as body text on a
 *   light surface, so it is used for active states, indicators and icons.
 *   --brand-dark (#771717) carries every piece of important text.
 *   Blue is gone entirely, including Leaflet's default popup link colour.
