/* Card Grader — neutral theme, card-type agnostic (Pokemon, sports, TCG).

   Colour discipline:
   - Grade severities ride a lightness ladder (none -> minor -> moderate ->
     major), so the table still reads as escalating severity in greyscale.
   - Red is reserved for "you should distrust this number" (unmeasurable
     edges, a low grade) — never decorative.
   - Light and dark are separately selected steps, not an inverted flip. */
