Bright, but still dark — matches ios!144

#3A0CA3 to #062C8C, saturation 0.93/0.96 where the old ground was 0.72/0.83.

🔴 Cards go DARKER than the ground, not lighter. Against a vivid ground a
raised card has to be lighter than a saturated violet, and secondary text then
falls below AA on it — every candidate measured did. Recessed panels invert it:
the gradient is the bright thing, content sits in dark wells.

    card #190B4E (1.47:1 vs ground) · field #2A1875 · secondary #B4BAD4
    avatar #31207F · danger #FF819F (was #FF6B92, 4.45:1 on the ground)

⚠️ The section band is a gap now, not a fill. It was 16pt of `surfaceVariant`,
which on the light theme was a barely-there grey seam — on the dark theme it
became a light purple slab drawing more attention than the sections it was
dividing. The panels either side of it are the separator.
