theme::space, theme::radius and theme::motion name the steps the UI is
drawn with. Literal gaps, corner radii and animation durations across ui/
now come from them, which folds a few near-misses onto the scale (10 and 14
point gaps onto 12, 10 point radii onto 12, 0.10 s hovers onto 0.12 s).
Page fades and toasts share one ease_out curve.
Player and library screens drop hardcoded blacks, whites and radii for
scheme roles and shape tokens, and use the shared button wrappers.
Continue watching was pinned above the poster grid, holding a fixed slice
of the screen on every scroll. It is now a full-span item at the top of the
grid, so it scrolls away with the rest.
storedPalette() reads and resolves the theme file without building the
engine, so onCreate can set the window background and system-bar icon
polarity before anything draws. Previously the background was a hex literal
in themes.xml and the bar icons were pinned dark, which meant every cold
start flashed one flavour's colour and Latte drew white icons on a
near-white page.
Adds the Material scheme mapping, type ramp and shape tokens the palette
feeds, plus unit tests for both.
