A floating action button that morphs into a dropdown quick-actions menu via GPU-composited `clip-path` animation — fully design-system agnostic.

A minimal uppercase text button whose accent outline grows from zero at the top-left corner on hover, changing from a gray idle border to an accent border at a consistent weight.

A gradient pill button where the text label slides up and a download icon slides in from below on hover — driven entirely by GPU-composited `translateY` transitions with no layout recalculation.

An amethyst gradient circle with a white chevron arrow that expands into a full pill on hover, sweeping under the label — a faithful port of the original circle-expand button, animated with GPU-friendly `clip-path` + `transform: scaleX()` instead of a width transition.

Circle icon button that morphs into a gradient pill on hover — the icon flies up as the label scales in, via a GPU-composited clip-path reveal.

A 3D card-flip button that rotates on hover to reveal a confirmation state using CSS perspective and `rotateY(180deg)` transform — fully design-system agnostic.

A pill-shaped button whose fill wipes in from the left edge: an overlay layer scales from scaleX(0) to scaleX(1) on hover and on keyboard focus, while the trailing icon chip inverts to the accent colour.

An ice-and-ink press button with a sharp-cornered ultramarine fill, 2px ink border, and a hard offset shadow that collapses as the button physically presses down into the page on click — powered by GPU-composited `transform: translate()` transitions.

Three vintage mechanical-keyboard keycaps — aged bone, faded retro-terminal orange, and worn black ABS — with domed tops, tall front skirts, and a deep physical press: the cap sinks, the skirt compresses, and the contact shadow tightens, all via GPU-friendly transforms and static shadow swaps.

A gradient button with a diagonal shine sweep animation that travels across the surface on hover, powered by GPU-composited `transform: translateX()` transitions — design-system agnostic.

An outlined button with a gradient border that sweeps diagonally from corner to corner on hover using a single clip-path transition and glow box-shadow — pure CSS, no JavaScript required for the effect.

A button that erases its idle label character by character and types in a confirmation label, with a blinking cursor that tracks the end of the visible text and a gradient border that draws around the button on hover.
