* @event lr-reveal-change - `detail: { envName, revealed }`.
* @event lr-copy - A clipboard write fulfilled. Frozen detail: `{ ok: true, text }`, where text is
*   the real (unmasked) value.
* @event lr-copy-error - A clipboard write failed. Frozen detail:
*   `{ ok: false, text, reason, error }`.
* @event lr-error - A clipboard write failed; compatibility notification without raw error text.
* @csspart base - The `<dl>` root.
* @csspart name - The `<dt>` name text.
* @csspart value-cell - The `<dd>` wrapping one entry's value text and its buttons; buttons live
* here (not as siblings of `<dt>`/`<dd>`) so the `<dl>` keeps a valid dt/dd content model.
* @csspart value - The value text itself; carries `data-masked`.
* @csspart reveal-button - The per-row reveal/hide toggle.
* @csspart copy-button - The per-row copy button.
* @cssprop [--lr-env-list-reveal-active-bg=var(--lr-color-brand-quiet)] - Background of a pressed
*   (revealed) reveal toggle.
* @cssprop [--lr-env-list-reveal-active-border=var(--lr-color-brand)] - Border color of a pressed
*   (revealed) reveal toggle. Restyling the pressed state otherwise requires overriding the
*   library-wide brand tokens, since `::part(reveal-button)[aria-pressed]` is invalid CSS.
* @status stable
