Port the sweeping highlight from the prototype: a 38%-wide white band
travels left to right on a 3.4s loop, idle for the first 62% so it reads
as an occasional flare rather than a constant shimmer. The tube mixes
now clip overflow so the band stays inside the button, and the loading
state suppresses it in favour of the existing pulse.
Drop the masked grid and scanline from the login page — low-contrast
texture behind a credential form makes the text harder to read. Only the
IsometricWave remains.
Brighten input text to near-white and bump it to 14.5px; Arco's default
--color-text-1 sits too dark on the recessed input fill. Avoid
-webkit-text-fill-color, which would defeat the password field's masking.
