   Wayfarer — travel journal portal
   Design language: warm paper, ink, and one deep accent. Deliberately NOT the
   emerald/dark console look of the ITAM portal next door: this portal is read
   on a phone in an airport at 6am, so it is light-first, high-contrast, and
   large-touch-target by default.
