{{-- One M3 list item: a headline with what leads it, what supports it and what trails it.

         <x-list-item title="holiday-photos.zip" description="248 MB · expires in 3 days" icon="folder_zip" trailing="3 files" />
         <x-list-item title="Settings" icon="settings" icon-right="chevron_right" link="/settings" />

     `title` (or the slot) is the body-large headline; `overline` sits above it (label-small),
     `description` under it (body-medium, up to two lines). The leading element is one of `icon`,
     `avatar` (an image URL, or initials in primary-container), `image` (a 56px thumbnail) or
     `video`, or a `leading` slot (a checkbox, a switch). The trailing element is `trailing` text
     (label-small), `icon-right`, or an `end` slot for controls (a menu, a switch). One-, two- and three-line
     heights (56, 72, 88px) follow from what is given, 16px between the item and what leads or
     trails it, and a three-line item top-aligns rather than centring — M3 aligns an item middle
     "by default, top-aligned if the item is 88dp+ or has 3+ lines of text". Its icons are 24px,
     or 20px in a `segmented` list, which is M3 Expressive's (ListTokens, androidx Compose
     Material 3, Apache-2.0).

     `video` is M3's leading media in its landscape size — a poster URL, or a `<x-slot:video>`
     holding a `<video>` or a thumbnail with a play badge. ListTokens gives it two: 100×56px in a
     two-line item and 114×64px in a three-line one (`LeadingVideoSmall` 56dp × 100dp,
     `LeadingVideoLarge` 64dp × 114dp — height first, both 16:9), so a video always lifts the item
     to at least the 72px two-line height, where 56 + 2×8 comes to 72 exactly, and to 88 with the
     large one, where 64 + 2×12 comes to 88. It takes the small corner the leading image takes
     (`ItemLeadingImageShape` = CornerSmall; the site publishes no separate video shape) and sits
     in the leading slot, 16px in from the edge like every other leading element. M3's slot model
     asks that the leading slot stay narrower than the content slot, so give an item with a large
     video the room its text needs
     (docs/reference/m3/components-actions-communication-containment.md § Lists → Anatomy, Specs).

     `link` makes the whole item the link. Otherwise, to make it open something while its trailing
     controls keep their own presses, give it `data-list-row` and put `data-list-open` on the one
     control that opens — see resources/js/list-rows.js. `selected` (true) is M3's selected item,
     in secondary-container; `disabled` greys it to 38%, drops its link and announces it
     `aria-disabled` — M3's states model treats disabled as not interactive, so a disabled item
     answers neither the pointer nor the keyboard.

     It takes its role from the `<x-list>` around it: a `listitem` in a plain list, where
     `selected` is `aria-current`, and an `option` announcing `aria-selected` in a `selectable`
     one. M3 asks for two cues on a selected item, never colour alone, so a selected option also
     draws a trailing check unless `icon-right` says otherwise. --}}
