Plan step 19, containment.md C-24. `interpolate-size: allow-keywords` was set and nothing transitioned, so the content snapped open. A new resources/css/components/collapse.css transitions `block-size` on `::details-content` over the fast spatial spring, with `content-visibility` `allow-discrete` beside it so the section stays rendered while it closes. The `<details>` carries `data-collapse` for the rule to find.

{{-- A section that opens to show more: an FAQ answer, advanced settings.

Not an M3 component; built on the native `<details>` so it opens without script, keeps its
|
|
state through a Livewire morph (`wire:ignore.self` stops the server's HTML from closing it),
|
|
and is announced as a disclosure. Drawn in M3's terms: a title-medium `title` (or a
|
|
`heading` slot), an optional leading `icon`, a chevron that turns over on the spatial spring,
|
|
and — where the browser supports animating `details` content (`interpolate-size`) — a height
|
|
that eases open on the same spring (`data-collapse`, resources/css/components/collapse.css).
|
|
`open` starts it open. `variant`: `plain` (the default, on the surface around
|
|
it) or `filled` (a surface-container tile with a large corner).
|
|
|
|
Its open state can be bound, both ways:
|
|
- `wire:model` (any modifiers; `.live` tells the server at once) entangles it with a Livewire
|
|
boolean property. The server renders `open` from the property, so the first paint matches it
|
|
and `open` is ignored; toggling writes the property, and the property changing opens or
|
|
closes it.
|
|
- `x-model` binds an Alpine property through `x-modelable`; `open` is then only the first
|
|
paint, until Alpine starts and applies the property.
|
|
The state lives in `collapseOpen` on the `<details>`, a name kept clear of `open`, which a
|
|
dialog inside the slot may be reading from a scope around it. Without a binding there is no
|
|
Alpine on it at all. --}}
