The stadium pill holds SVG usage and time rings, pill-shaped tail bars and
the payload's texts, laid out in physical px from canvasW, canvasH and dpi
with the GDI bubble's formulas (ui/layout.js, unit-tested). The palette is
CSS custom properties per theme; fills come from Rust. The ring arc, weekly
fill and weekly percent pulse at 95% and above on an 80 ms step, and the
time progress advances every minute.
Only the pill takes pointer input, so the corners are dead. A press that
moves 3 physical px starts an OS drag after arming the move end; an earlier
release is a click. Right-click opens the native menu and Ctrl+wheel resizes.
@tauri-apps/cli is a local devDependency. ESLint runs the recommended
and JSDoc rules, with browser globals for ui/ and node globals for tests
and scripts. npm test runs node --test over tests/js.
