Let a card's title take the heading level the page needs

<x-card> always titled itself with an <h3>, so a card straight under a
page's <h1> skipped a level, which SealShare's download page did with
no way round it from the application. `heading` takes h2 to h6, or div
or p for a title that is not a heading, as <x-pane> and <x-app-bar>
already do; h3 stays the default. The skill also says a card holds one
subject, as M3 does (plan step 46).

`variant`: `filled` (default, surface-container-highest), `elevated`, `outlined`; medium corner. Props `title`, `subtitle`, `separator`; slots `figure` (full-bleed media), `menu` (top-end), `actions` (end-aligned). Do not pass `bg-*`; use `variant`.
`variant`: `filled` (default, surface-container-highest), `elevated`, `outlined`; medium corner. Props `title`, `subtitle`, `separator`, `heading` (the title's element, `h3` by default: pass `h2` for a card straight under the page's `h1`); slots `figure` (full-bleed media), `menu` (top-end), `actions` (end-aligned). A card holds content and actions about one subject (M3); a table of many rows or a group of settings is a headed section, not a card. Do not pass `bg-*`; use `variant`.
A card or list item that opens something is a **row**: `data-md-list-row` on it and `data-md-list-open` on its one opener (the title link or a button). A press anywhere else on the row reaches the opener; its other controls keep their own presses. Never wrap a card in `<a>` or use a stretched link. A row answers with the state layer and one step of elevation; its corner does not move.
