  ----------
  Every color, font, radius and spacing value on the site lives here.
  Restyle the site by changing these values. Nothing in main.js depends on them.

  Layout concept: a left-aligned ledger. A narrow label column on the left,
  content on the right, the way a research note or a resume is ruled.
  The drifting 3D forms are the one loud element. Everything else stays quiet.
