/**
 * Sidebar foot card: the compact usage glance seated below the shell sidebar's
 * Settings row. It is deliberately a GLANCE, not the panel the 2026-09-18
 * removal took out. Two states, persisted across reloads:
 *
 * - expanded (default): a price-first headline (today's estimated spend,
 *   falling back to today's tokens when nothing priced was recorded), a
 *   tokens/calls line, up to two configured-provider balances, and an
 *   updated-at footer;
 * - collapsed: a one-line strip with the gauge glyph, the spending
 *   provider's name, the label and the headline value.
 *
 * The card body is one button that opens the settings panel on the usage
 * section, so detail lives in exactly one place; the corner chevron toggles
 * the collapse state (sibling buttons — buttons inside a button are invalid
 * HTML).
 *
 * Data comes from the same shared store the settings section reads; the card
 * runs its own relaxed poll loop (30 s, visible-tab only) because the sidebar
 * foot is permanently mounted. The card disappears while the plugin is
 * disabled (settings flag) or while the host serves no usage routes (a 404
 * means the host half is off), matching the section's own gating.
 * @module @linxin666/dsh-usage/client/UsageFootCard
