Loaders
The orbs are bezel's own, and what a thinking surface should reach for:
use ui::loaders::{self, Orb};
loaders::orb(Orb::Cluster, "thinking", 44.0, &theme, cx.entity_id(), cx)One function with a shape parameter rather than four functions: they are the same operation, and the thing that differs is an argument. Cluster is blobs whose sizes swing so the count you perceive changes; Ring is dots on a circle with the brightness chasing round; Converge gathers them to a point and opens back out; Bloom is rings leaving the centre and fading before the edge — the only one that travels outward, which is what makes it read as a signal rather than a wait.
Everything is circles, because that is the vocabulary gpui gives at the pinned rev: no rotation transform, no conic gradient, no blur filter on an element. So the glow is a BoxShadow, the ring is eight positioned dots rather than a swept arc, and every position is arithmetic — all of it pure and unit-tested in motion::phase.
One tint, from the theme's accent. In three hues this would be the gradient spinner wearing a different shape.
The older three are grids of cells: pulse_loader (a row), gradient_spinner (3×3) and mini_gradient_spinner (2×3). loading_word is the spaced "L O A D I N G" caption that goes under one.
They all take the calling view's EntityId and drive off the shared 30fps pulse clock rather than a per-element repeating animation, so instances stay phase-locked and the clock parks when the last one unmounts. Cells animate inside fixed-size slots — opacity and inner size are paint-local and never move the layout around them. Reduced motion snaps every cell to its rest state.
