     kit dark=--ink · accent=--sun · accent-ink=--sun-deep (text on light) ·
     accent-on-dark=--sun (text on the brand dark) · accent-light=--sun-bright
     (BACKGROUNDS/hover only, never text) · accent-2=--sun-soft.
     --ink-2/--ink-3 are local shades of the brand dark for gradients; --ink-3 is
     capped at #19493B because the kit's accent-on-dark is derived against #0F3229
     and stops passing 4.5:1 on anything lighter. */
