/*
 * Campfire — Reveal.js Theme
 * A warm trail-guide aesthetic for Scouting presentations
 * by Tyler Malone
 *
 * Standalone theme — replaces black.css entirely.
 * Overrides Reveal's --r-* variables so structural rules work correctly,
 * then layers custom styling on top.
 *
 * Design language: kraft paper, trail maps, field guides.
 * Light warm background — the opposite of the dark starfield theme.
