Plan step 36 (containment group): <x-modal>'s class lists move into resources/css/components/modal.css, keyed on data-md-modal (with data-md-fullscreen) and data-md-modal-box/-bar/-head/-title/-subtitle/ -body/-content/-actions. Sizes stay px (560/280/48px matching DialogTokens.kt/FullScreenDialogTokens.kt and the 56px full-screen header, C-17), spacing the measurement tokens, breakpoints a literal 600px range query. The phone-only header bar and the pinned head/actions keep their existing responsive behaviour (a subtitle or an icon keeps the head on screen below 600px; only the bar's own divider-eligibility needs a computed flag, since it alone can sit beside a head that is also on screen) — reproduced with :has() against data-md-icon/ data-md-modal-subtitle wherever that is self-contained, and with an explicit data-md-modal-divider attribute where it is not. The scroll-driven dividers rename data-dialog-head/-actions -> data-md-modal-head/-actions, data-overflow-top/-bottom -> data-md-overflow-top/-bottom (resources/js/dialog.js); the dialog-dividers Alpine directive keeps its name, since it isn't a data-md-* hook. resources/css/components/dialog.css (Tailwind-era) is replaced by modal.css, imported from the Containment block of components.css; its import leaves resources/css/tailwind.css. No other component renders <x-modal> or dialog.css's rules (checked: datepicker, timepicker and search draw their own dialog-shaped surfaces independently).

/**

|
* `x-dialog-dividers`, on `<x-modal>`'s body — the one part of a dialog that scrolls: marks the
|
|
* `<dialog>` with `data-md-overflow-top` while the body is scrolled away from its top, and
|
|
* `data-md-overflow-bottom` while more of it is below. resources/css/components/modal.css draws
|
|
* those as the dividers under the pinned header and over the pinned actions; a body that fits
|
|
* marks neither.
|
|
*
|
|
* The marks go on the `<dialog>` rather than the body because the dialog is `wire:ignore.self`: a
|
|
* Livewire morph hands the body back the server's attributes, which would wipe a mark until the
|
|
* next scroll, but it never touches the dialog's own.
|
|
*
|
|
* Measured on scroll, and whenever the body or what is in it changes size: the body when the window
|
|
* or the dialog does (opening, too — a closed dialog has no size, and the observer reports the
|
|
* one it opens to), and the element the component wraps around the slot when a morph, an image or
|
|
* a disclosure makes the content taller or shorter while the body stays at its cap.
