/**
* `<lr-poll-status>` — a "next scheduled refresh" countdown with a built-in pause control: a
* ticking `M:SS` display counting down to the next scheduled action, a "Refreshing…" state at
* zero, a localized inactive state while `active` is false, a "Paused" state
* while `paused` (instead of freezing on a stale value), and a pause/resume
* toggle. First-party invention (no Web Awesome equivalent); the
* closest existing component, `lr-stream-status`, is scoped to transport/connection-health
* phases, a different concern from a scheduled-interval countdown -- this mirrors its internal
* `<lr-live-region>` composition for accessible phase-transition announcements.
*
* Long translated labels wrap within the allocated inline size while the pause/resume
* action retains its minimum target size.
*
* @customElement lr-poll-status
* @event lr-poll-due - Fired once when the countdown reaches zero (not fired while `paused`).
* @event lr-pause-change - Fired when `paused` changes via the built-in button.
*   `detail: { paused: boolean }`.
* @csspart base - The root wrapper.
* @csspart indicator - The pulsing status dot.
* @csspart countdown - The localized `M:SS` text, or the refreshing, paused, or inactive state.
* @csspart pause-button - The built-in pause/resume toggle.
* @cssprop [--lr-poll-status-due-bg=var(--lr-color-success)] - Background of `indicator` while
*   `data-due` is set, without repainting every other component that reuses the shared success
*   token.
* @cssprop [--lr-poll-status-pause-hover-bg=var(--lr-color-brand-quiet)] - `pause-button` hover
*   background.
* @cssprop [--lr-poll-status-pause-hover-color=var(--lr-color-brand)] - `pause-button` hover
*   foreground.
* @cssprop --lr-poll-status-pause-active-bg - `pause-button` pressed background; defaults to the
*   former brand-quiet active mix.
* @cssprop [--lr-poll-status-pause-active-color=var(--lr-color-brand)] - `pause-button` pressed
*   foreground.
* @status stable
* @since 4.0.0
