/**
* `<lr-result-card>` — a small bordered card shell for a custom tool-result
* renderer's body (see `<lr-tool-result-view>`'s `registerToolRenderer()`
* in `../tool-result-view/registry.js`). Purely visual, with no state of its
* own beyond slot-presence tracking: it gives every custom renderer the same
* "small card" language (border, radius, optional heading + header actions)
* without each one hand-rolling its own box.
*
* Pairs with `<lr-result-field>` for the label/value rows that typically
* make up the body, though the default slot accepts any content — nothing
* here requires a `<lr-result-field>` specifically.
*
* @customElement lr-result-card
* @slot - The card body — typically one or more `<lr-result-field>` rows.
* @slot actions - Small header controls (e.g. a copy button), rendered
* alongside the heading.
* @csspart base - The outer bordered container.
* @csspart header - The header row wrapping the heading and the `actions`
* slot. Present in the DOM at all times (so a later `slotchange` on
* `actions` is still observed) but `hidden` whenever there is no `heading`
* and no `actions` content — an untitled, action-less card has no visible
* header bar at all.
* @csspart heading - The heading text. Truncates with an ellipsis and carries
* its own native `title` attribute (the full string) so hovering the
* truncated text reveals it. The host's native `HTMLElement.title` remains
* independent and is never repurposed or removed.
* @csspart actions - The wrapper around the `actions` slot. `hidden`
* whenever the slot has no assigned content.
* @csspart body - The wrapper around the default slot.
* @cssprop [--lr-result-card-compact-header-padding=var(--lr-space-xs)] - `[part="header"]`
*   block/inline padding while `compact`.
* @cssprop [--lr-result-card-compact-header-gap=var(--lr-space-xs)] - Gap between `[part="header"]`'s
*   heading and actions while `compact`.
* @cssprop [--lr-result-card-compact-body-padding=var(--lr-space-xs)] - `[part="body"]` padding
*   while `compact`.
* @cssprop [--lr-result-card-compact-body-gap=var(--lr-space-2xs)] - Gap between `[part="body"]`'s
*   children while `compact`.
* @cssprop [--lr-result-card-background=var(--lr-color-surface)] - Fill of the outer card
*   (`[part="base"]`) while `frame="card"`. `frame="plain"` still removes the fill entirely.
* @cssprop [--lr-result-card-border-color=var(--lr-color-border)] - Colour of the outer card's
*   border and of the `[part="header"]` divider.
* @cssprop [--lr-result-card-radius=var(--lr-radius)] - Corner radius of the outer card.
*   `frame="plain"` still squares the corners.
* @status stable
* @since 4.0.0
