# llimphi-widget-fab Floating Action Button. A raised circular button for a screen's **primary action** (compose, new, +, capture). It inherits the Material/Flutter pattern: at rest over an E3 shadow, a circle in the `accent` colour, a centred white glyph, and **hover feedback** (the fill brightens under the cursor, through the compositor's `hover_fill` — no state in the host). The **entrance** uses `animated_pop_in` for Material's canonical "pop" (scale 0.6 → 1.0 + fade-in) instead of appearing abruptly. --- Part of **llimphi** — see [llimphi](../../README.md).
