/* ============================================================
   Darkroom 8 · IKEA Frame Print Guide
   Built in the print calculator's system (printing.darkroom8malaysia.com):
   one quiet card on paper, hairlines instead of boxes, tiny uppercase
   eyebrows, plain-text pickers with a red dot, numbered rows, red
   dimension callouts, one black pill for the next action.
   Tokens live in theme.css. Pixel sizes mirror the calculator's
   Tailwind classes (text-[9px] tracking-[0.2em] etc.).
