Plain refraction
The restrained version: backdrop blur plus a saturation lift, one hairline rim, and a top-edge highlight. No animation until hover, where the blur deepens. Safest across every ground colour on the site.
Lensed pill
Reads as a solid lens rather than a pane: an inset ring fakes the thickness of the glass, and the edges pick up more light than the middle, the way a real convex pill would.
Specular sweep
A highlight that tracks the pointer across the face, so the glass catches light as you move over it. Falls back to a static highlight where the pointer can't hover.
Squish on press
The liquid part is the behaviour, not the surface: the pill deforms slightly under the press and settles back with a spring, so it feels like a soft body rather than a rectangle.
Frosted slab with drip
The most physical of the five — heavier frost, a visible bottom lip where the glass is thickest, and a bead of light that slides down the rim on hover. Best on photography, busiest on flat colour.
All five, side by side
The same five treatments over one photograph and then over flat brand colour, since glass lives or dies on what is behind it. Toggle the ground to compare.
