/* Card Grader — slab-house theme: silver ground, red accent, black text.
   Card-type agnostic (Pokemon, sports, TCG).

   Committed light, not a light *mode*. A single deliberate look; a
   half-tended second palette is how a design drifts out of sync with
   itself. Phones in dark mode get this same design, which is the intent.

   Colour discipline:
   - Grade severities ride a lightness ladder (none -> minor -> moderate ->
     major), so the table still reads as escalating severity in greyscale.
   - Red is the BRAND here, so it can no longer also mean "distrust this
     number". Severity red is therefore a distinctly darker, browner red
     (--critical) than the brand's (--brand), and severity is never carried
     by colour alone — the pills and chips carry a word too.
   - Foil/holo treatment is reserved for a 10. Every card shimmering would
     say nothing. */
