The extraction dropped the old banner's `spinner` class on the glyph
span (`el('span', { class: 'glyph spinner' }, ...)`) - JobqRollup.tsx
rendered a static `.jqr-glyph` with no animation rule anywhere.
`.spinner` (shared/base.css) is already imported by both consumers, so
just reuse it on the glyph rather than duplicating the keyframes.
argus caught this on review - a single-frame screenshot can't tell a
frozen spinner from a missing one, which is exactly why it slipped
past the PR's visual verification.
