/* =====================================================================
   andy-barber.co.uk — a TUI

   The portfolio built as a terminal application, in the lineage of k9s,
   lazygit and btop: bordered panels with titles set into the top rule,
   a tree for the career log, ls-style colouring for the skill list,
   a persistent status bar, and keybindings that actually work.

   Not a fake shell prompt with a typing animation. An application.

   One typeface, as a terminal has: Martian Mono. Its width axis carries
   the hierarchy — condensed for dense rows, expanded for the banner.

   Palette is a 16-colour terminal scheme, dark by default because a
   terminal is, with a light scheme for those who run one. Every ink
   value clears 4.5:1 on both surfaces it sits on; the steps were solved,
   not eyeballed.
