/* ==========================================================================
   Ryan Walsh — Portfolio
   Light pages with a navy/violet gradient hero, after aphex.co. Violet is the
   interface accent; the pink "pen" marks the hand-drawn annotations. The
   lime/teal come from Ryan's own TapSOS work and only appear inside project
   imagery. --paper is the text colour and --ground the background: .on-dark
   swaps them for navy sections.
