/*
 * Europe 2026 — a cute paper travel journal you can still read at arm's length
 * on a station platform.
 *
 * The look: warm cream paper, sage green, a serif with real character
 * (Fraunces) for headings, a handwritten script (Caveat) for the little
 * flourishes, dotted timeline rails, and a soft watercolor vignette per city.
 *
 * Three display modes, cycled from the header:
 *   light  default — the journal
 *   dark   evenings and dim train carriages, same palette by candlelight
 *   sun    direct sunlight — pure black on pure white, heavier weights, larger
 *          base size, thicker rules. Not "light mode with more contrast": every
 *          mid-tone is removed, because mid-tones are what disappear in glare.
 *
 * Nothing here is smaller than 15px, and nothing tappable is under 44px.
