Glow Card

Purpose

An ambient bloom sitting behind the card that widens on hover — not pointer-tracked. It glows from its own center outward regardless of where the pointer actually is, closer to a halo than a light source.

Good for

• a card that should read as lit from within, independent of exactly where the pointer is
• a shared visual identity across a small set of featured cards

Avoid for

• a surface that should light up specifically where the pointer touches it — that's Spotlight Card (lighting the face) or Glow Border (lighting the edge), both pointer-tracked, unlike this one

Recommended defaults

color defaults to the blush accent; pass a cloud token for a cooler read. Don't reach for a hue outside the family's blush/cloud pair — same "no new hue" rule as everywhere else in this document set.

Accessibility

• Same focus-visible rule as Basic Card once onClick/href is present.
• The glow is a decorative, aria-hidden overlay.

Performance

Pure CSS opacity/blur, no pointer-event listeners. The glow is visible at rest either way; only its widening on hover is motion-safe:-scoped, so prefers-reduced-motion: reduce still shows a glow, just a static one.

Composition

The family's shared shape lives in docs/card-api-conventions.md — read that once, not per card.
