/**
* `<lr-commit-card>` — compact commit summary (subject, author/time, diffstat, per-file changes)
* that links file rows out to a diff view. Set `compact` (tighter padding) and/or
* `frame="plain"` (no border/padding at all) when embedding one as a row in a commit list or
* PR timeline, so the built-in card chrome doesn't double up against the list's own — same
* convention as `<lr-agent-run>`'s own `compact`/`frame`.
* Duplicate file paths normalize before totals, counts, rendering, and selection events; the
* first occurrence wins. File addition/deletion counts are normalized to finite non-negative integers before totals,
* localized display, and accessible summaries are derived.
*
* Public collection properties take bounded, clone-owned readonly snapshots. Create a new
* collection and reassign it after changes; mutating the assigned array does not update the view.
*
* @customElement lr-commit-card
* @event lr-file-select - `detail: { filePath }` — a file row was activated.
* @event lr-toggle - `detail: { collapsed }` — the file-list fold changed.
* @event lr-copy - `detail: { ok: true, text }` — the full-hash clipboard write completed.
* @event lr-error - The clipboard write failed; generic no-detail notification.
* @event lr-copy-error - `detail: { ok: false, text, reason, error }` — typed clipboard failure.
* @slot actions - Trailing header controls (e.g. an "open PR" button).
* @csspart base - The root wrapper.
* @csspart subject - The commit message's first line.
* @csspart body - The commit message's remaining lines.
* @csspart hash - The abbreviated hash text.
* @csspart meta - The author/time/diffstat row.
* @csspart author - The author text.
* @csspart time - The `<time>` wrapper.
* @csspart diffstat - The aggregate `+N -M` summary.
* @csspart additions - The additions count.
* @csspart deletions - The deletions count.
* @csspart files-toggle - The file-list fold toggle.
* @csspart file - A file row; carries `data-status`.
* @csspart file-path - A file row's path text.
* @csspart file-status - The one-letter git-status badge inside `[part="file-path"]`, present only
*   when that file has a `status`. Carries the localized expansion (`Modified`, `Added`, ...) as its
*   accessible name, so the bare letter never reaches assistive tech on its own.
* @csspart file-additions - A file row's additions count.
* @csspart file-deletions - A file row's deletions count.
* @csspart copy-button - The hash copy button.
* @csspart actions - The `actions` slot wrapper.
* @cssprop [--lr-commit-card-compact-padding=var(--lr-space-s)] - `[part="base"]` padding while
*   `compact`.
* @cssprop [--lr-commit-card-background=transparent] - Fill of the outer card (`[part="base"]`)
*   while `frame="card"`, unset by default so the card takes the surface it sits on.
*   `frame="plain"` still removes the fill entirely.
* @cssprop [--lr-commit-card-border-color=var(--lr-color-border)] - Colour of the outer card's
*   border.
* @cssprop [--lr-commit-card-radius=var(--lr-radius)] - Corner radius of the outer card.
*   `frame="plain"` still squares the corners.
* @status stable
* @since 4.0.0
