Shimmer Tuner

Spike A · CSS only. Find the floor: the most dialled-back sweep that still reads working, not frozen. Copy the spec below when it feels right.

% white mixed into the peak. The key knob. Shipped libs use ~3%. Try tuning down until it nearly disappears, then back off one notch.
How long one band-crossing takes. Slower reads calmer.
Dark pause between sweeps. Intermittent beat continuous on perceived-wait studies.
Width of the bright zone. Wider = softer, more diffuse.
Tilt off-horizontal. Note: this is the one param that CANNOT port to a 1-D terminal.
react-loading-skeleton uses ease-in-out; wave sweeps often linear. Evidence is mixed.
