/* DripTorch — field-ready marketing theme.
 * Design notes:
 *  - Light theme primary; high contrast for outdoor sun + smoke.
 *  - 56px+ touch targets — usable with gloves and dirty hands.
 *  - System font stack; no webfont fetch (flaky tower-camp connections).
 *  - Generous type scale (base 17px desktop / 18px mobile).
 *  - One bold accent (safety orange); rest is ink-on-cream.
