secondary used a flat, static tint that only worked over a plain
surface, so it looked out of place on the hero's hue-shifting gradient.
Add a backdrop blur (no border, per feedback) so it always reads
against whatever's actually behind it. Gave the button its own
background tokens instead of aliasing --mf-surface-2, and dropped the
now-unused --color-btn-glass tokens left over from the removed glass
variant.
