   Cause of the disorder: object-fit:contain inside frames whose
   aspect-ratio did not match the image, on two different mat
   colours, with a hand-typed 76px stagger on the first figure.
   Tokens confirmed defined before use: --archive (history.css:2),
   --panel-2 --ink --ink-soft --line --brass --dark-line --sans.
   The site defines no spacing, gap or rhythm tokens, so the three
   --fig-* vars below are component-scoped, following the
