/* ============================================================
   chandhan.com: the contact sheet.
   The home page is black photo paper: one full-bleed print, then
   the work as frames on a strip, marked in grease pencil. Every
   other page is the back of a print: paper, typed labels, hairlines.
   One accent, the grease pencil red. No gradients on chrome, no
   shadows, no tints. Legacy tokens (--fg, --rule, --ok ...) stay
   defined because the demos read them at mount.
