 *             hue at alpha=0 — avoids the rgba(0,0,0,0) black-bleed
 *             anti-aliasing artifact on dark backgrounds), muted text.
 *             Buttons read as labelled text glyphs at rest.
 *
 *   Hover     border alpha-fades in, text brightens, scale(1.03) lift,
 *             soft layered outer glow (3px halo + 16-18px blur).
 *             Background max 10% opacity tint — no solid fills.

 *   Active /  Bright text + soft persistent border + 8-10% tint.
 *   Selected  State communicated through colour, never a filled box.
 *
 * transition: 0.2s ease-in-out on all animating properties.
