/*
* An extended FAB that collapses to a FAB while the page scrolls down (`<x-fab
* collapse-on-scroll>`, resources/js/fab.js sets `data-collapsed`). M3's extended FAB page: it
* "can collapse to a FAB on scroll-down and re-expand to extended on scroll-up — when switching
* between FAB↔extended FAB, shape changes, the icon moves left, and the text label fades in/out".
*
* `width: auto` cannot transition, so the label sits in a one-column grid whose track closes to
* zero; that track is what animates, and the button lays itself out around it every frame. The
* gap and the minimum width go with it, all on the default spatial spring — the size of morph
* `state-transition-default` is for — while the label fades on the effects spring. The collapsed
* sizes are the FAB's own (FabBaseline/Medium/LargeTokens: 56/80/96px). The extended FAB's
* padding already centres the glyph at `sm` (16px + 24px + 16px) and `md` (26 + 28 + 26); at
* `lg` its 28px is 4px short of the 32px that centres a 32px glyph in 96px, so that one moves.
* Corners do not change: each size's FAB and extended FAB share one.
*
* The transition list repeats the FAB's own shadow and colour transitions, which this rule
* replaces. Under reduced motion tokens/motion.css takes every duration to zero, so it swaps.

/*
* <x-badge>: M3's small and large badges, and the library's status label.
*
* BadgeTokens (androidx Compose Material 3, Apache-2.0): the small badge is a 6px dot
* (`data-md-dot`), the large badge 16px tall and at least 16px wide with 4px either side of a
* `label-small` count in tabular figures, both fully round and `error` by default. A floating
* badge sits on M3's anchor geometry at the top-end corner of its `position: relative` parent: the
* dot flush in the corner, the count 2px above it with its start 12px in from the parent's end.
*
* The status label (`data-md-variant`) is not an M3 badge: 24px tall, small corner, 8px either
* side, 4px between an icon and its word, `label-medium`. `tonal` draws it in the colour's
* container, `solid` in the colour itself, `outline` as a 1px `outline` edge around
* `on-surface-variant` text — `outline` rather than `outline-variant`, because M3 asks a badge for
* 3:1 against what is behind it and `outline-variant` is the decorative role dividers use.
*
* `data-md-color` picks the pair of roles; `neutral` has no hue of its own (`on-surface-variant`
* and `surface`, or `surface-container-high` behind `on-surface-variant` text), and `plain` sets
* no colour at all, so the caller's CSS paints it.

/*
* <x-button-group>: related buttons in a row, and the shapes a button takes from its place among
* its siblings. The connected form is also what `<x-group>` draws its segments with, which is why
* its stylesheet imports this one. A group never wraps: M3's rule, and the press expansion only
* reaches a neighbour on the same line anyway.
*
* Standard (`data-md-button-group="standard"`): the buttons stand apart — 18/12/8/8/8px by size
* (ButtonGroupXSmall…XLargeTokens.BetweenSpace) — and pressing a label button widens it and
* narrows its neighbours by the same amount, so the row keeps its length: Expressive's press
* expansion (ButtonGroupDefaults.ExpandedRatio is 15%; this uses a fixed step per size, 4/6/8/16/
* 20px, on the button's own padding of 16/16/24/48/64px). Icon buttons keep their width. A square
* standard group has no inner edges, so it hands its buttons the square corner scale
* `<x-button shape="square">` draws (12/12/16/28/28px, 8/8/12/16/16px under the finger), and a
* selected button in it turns round.
*
* Connected (`data-md-button-group="connected"`): 2px apart, the outer corners full, the inner
* corners small, smaller still while pressed, and a selected segment (`aria-pressed`, or a checked
* input inside it) fully round — ConnectedButtonGroupXSmall…XLargeTokens and the M3 Expressive
* connected button group spec: inner corners 4/8/8/16/20px, pressed 2/4/4/12/16px. At the two
* smallest sizes a segment is 32px or 40px tall, and M3 names both numbers it must not go below:
* "XS and S connected button groups have a 48dp target area and a 48dp minimum width".
*
* Shape (`data-md-shape="square"`, M3's "Default shape | Round, square" configuration):
* `--md-button-group-outer` is what the two ends of a group round to — half the height for a round
* group, and for a square one the corner its inner edges take, which is the square table M3
* publishes for connected groups (4/8/8/16/20dp by size). Selection morphs the other way: M3 has a
* toggle inside a group "swap shape square/round on selection", so a selected segment in a square
* group turns round, which is why the selected rule keeps `--md-button-group-full`.
*
* "Full" is half the size's height (16/20/28/48/68px), never `--md-sys-shape-corner-full`'s
* 9999px. One element mixes full outer corners with small inner ones, and when a box's radii add
* up to more than its side, CSS scales every radius by the same factor: a 9999px corner beside an
* 8px one shrank the 8px one to a hundredth of a pixel, so the inner corners drew square.
*
* <x-button>'s own corner rules carry no specificity, so these reshape the buttons in a group
* whatever selector they use; a pressed or selected segment changes one custom property and the
* outer corners stay put.

/*
* <x-button>: M3 Expressive's buttons — label button, icon button and toggle — and the page's
* create action that is a FAB on a compact window.
*
* Geometry from androidx Compose Material 3's tokens (Apache-2.0), per `data-md-size`:
*
* size height label padding gap type icon (label / icon-only) outline square pressed
* xs 32px 16px 8px label-lg 20 / 20px 1px md sm
* sm 40px 16px 8px label-lg 20 / 24px 1px md sm
* md 56px 24px 8px title-md 24 / 24px 1px lg md
* lg 96px 48px 12px headline-sm 32 / 32px 2px xl lg
* xl 136px 64px 16px headline-lg 40 / 40px 3px xl lg
*
* (ButtonXSmall…XLargeTokens; the xs padding is the 16px Phase D settled on, ACT-09.) An icon button
* (`data-md-icon-button`) is as tall and `narrow`, `default` or `wide` across by
* XSmall…XLargeIconButtonTokens: 28/32/40, 32/40/52, 48/56/72, 64/96/128 and 104/136/184px. The
* views size the glyphs through `<x-icon size>`; `--md-button-icon` carries the same size for the
* loading indicator that stands in for the glyph while the button's action runs.
*
* Shape: round (`--md-sys-shape-corner-full`) by default; `data-md-shape="square"` and a selected
* button take the size's square corner, a selected square icon button turns round, and every one
* squares off to the pressed corner under the finger. Those corner rules are wrapped in `:where()`,
* so they carry no specificity at all: a group's stylesheet (button-group.css, split-button.css)
* reshapes the buttons inside it with any selector, without a specificity fight.
*
* Colour: `data-md-color` picks the roles a variant draws with; the variants set
* `--md-button-container`, `--md-button-label`, `--md-button-outline` and `--md-button-elevation`,
* which one rule paints, so the disabled treatment (on-surface at 10% behind 38% text,
* FilledButtonTokens.DisabledContainerOpacity and DisabledLabelTextOpacity) replaces them with a
* plain declaration. Primary's tonal button is secondary-container and its standard icon button
* on-surface-variant, as M3 draws them; the text button's label is primary, as Compose draws it,
* not the token's on-surface-variant, which its own source marks as wrong; a selected text button
* takes the tonal container (the library's deliberate deviations, docs/audits/m3-alignment).
*
* Motion: corners, padding, margins and `bottom` on the fast spatial spring, colour and shadow on
* the fast effects spring beside it — a colour must never overshoot (tokens/motion.css).
*
* The state layer, focus ring and 48px target (xs and sm) are the declarations of the foundation's
* `md-state-layer`, `md-focus-ring` and `md-touch-target` (foundation/interaction.css), keyed on
* the button itself.
*
* `data-md-compact-fab`: below `medium` (600px) the button is an extended FAB in the thumb zone —
* fixed 16px from the end, 56px tall with 16px padding, the large corner, `title-md`,
* primary-container at elevation 3 (ExtendedFabPrimaryTokens) — lifted clear of a bottom bar and
* of a snackbar on screen (`--material-bottom-bar`, `--material-snackbar-height`), because M3 puts a
* snackbar above a FAB and never over one. From `medium` it is the button it was written as.
* `data-md-responsive` on the label hides it below `expanded` (840px).

/*
* <x-fab>: M3 Expressive's floating action button and extended FAB.
*
* FabBaseline/Medium/LargeTokens and ExtendedFab*Tokens (androidx Compose Material 3, Apache-2.0),
* per `data-md-size`:
*
* size FAB corner glyph extended: min width gap padding type
* sm 56px lg (16px) 24px 80px 8px 16px title-md
* md 80px lg-increased 28px 80px 16px 26px title-lg
* lg 96px xl (28px) 32px 96px 20px 28px headline-sm
*
* A FAB and its extended form share the height and the corner. `data-md-color` is `primary`,
* `secondary` or `tertiary`, drawn in its container (`data-md-variant="container"`) or in the
* colour itself (`filled`), at elevation 3, 4 under a hovering pointer, the shadow and colours on
* the fast effects spring. The state layer and focus ring are the declarations of the foundation's
* `md-state-layer` and `md-focus-ring`. `data-md-fab` on the root is also the hook a place uses to
* draw a nested FAB its own way: a navigation rail or a docked toolbar flattens it to elevation 0.
*
* `data-md-collapse-on-scroll` is M3's extended FAB that "can collapse to a FAB on scroll-down and
* re-expand to extended on scroll-up — when switching between FAB↔extended FAB, shape changes, the
* icon moves left, and the text label fades in/out" (resources/js/fab.js sets
* `data-md-collapsed`). `width: auto` cannot transition, so the label sits in a one-column grid
* whose track closes to zero; that track is what animates, and the button lays itself out around
* it every frame. The gap and the minimum width go with it, all on the default spatial spring,
* while the label fades on the effects spring. The collapsed width is the FAB's own size. The
* extended padding already centres the glyph at `sm` (16 + 24 + 16) and `md` (26 + 28 + 26); at
* `lg` its 28px is 4px short of the 32px that centres a 32px glyph in 96px, so that one moves. The
* label stays in the accessibility tree — clipped and transparent, never `display: none` — so the
* collapsed FAB keeps the name the extended one had. Under reduced motion tokens/motion.css takes
* every duration to zero, so it swaps.

* segments that share the row, or hug their labels with `data-md-inline`.
*
* The segments are M3's buttons at the group's `data-md-size` (Button*Tokens: 32/40/56/96/136px
* tall, 16/16/24/48/64px either side, 8/8/8/12/16px between icon and label, label-large, label-
* large, title-medium, headline-small, headline-large), with the connected shape from
* button-group.css: 2px apart, small inner corners, the chosen segment fully round. At `xs` and
* `sm` a segment carries M3's 48px target and a 48px minimum width, which M3 asks for by name.
*
* `data-md-variant` is the toggle button's colours: `tonal` (secondary-container, chosen in
* secondary), `filled` (surface-container behind on-surface-variant, chosen in primary) or
* `outlined` (an outline-variant edge, chosen in inverse-surface). A checked input picks the
* chosen colours (`:has(:checked)`), a disabled one the disabled treatment — on-surface at 10%
* behind 38% text — and keyboard focus on the input draws M3's focus ring around its segment.
* Corners move on the fast spatial spring and colours on the fast effects spring beside it.
*
* The legend is label-large and the hint body-small, both in on-surface-variant; a validation
* message takes the hint's place in error. `hint-class` lands on the hint, where a caller's class
* outranks the colour here.

/*
* Button groups and split buttons: shapes that depend on a button's place among its siblings.
*
* Unlayered on purpose. Each <x-button> draws its own corners and padding as utilities, and a
* rule in any @layer loses to a utility whatever its specificity; the group has to win.
*
* Standard group (`<x-button-group>`): pressing a label button widens it and narrows its
* neighbours by the same amount, so the row keeps its length — Expressive's press expansion
* (ButtonGroupDefaults.ExpandedRatio is 15%; this uses a fixed step per size). Icon buttons keep
* their width.
*
* Connected group (`<x-button-group connected>`, `<x-group>`): 2px apart, the outer corners
* full, the inner corners small, smaller still while pressed, and a selected segment fully round
* (ConnectedButtonGroupSmallTokens and the M3 Expressive connected button group spec).
*
* Shape (`shape="square"`, M3's "Default shape | Round, square" configuration): `--group-outer`
* is what the two ends of a group round to — half the height for a round group, and for a square
* one the same corner its inner edges take, which is the square table M3 publishes for connected
* groups (4/8/8/16/20dp by size). A square *standard* group has no inner edges, so it hands its
* buttons the square corner scale `<x-button shape="square">` draws (`--group-square`, and
* `--group-square-pressed` under the finger) instead of asking the caller to write it on each
* one. Selection morphs the other way in both: M3 has a toggle inside a group "swap shape
* square/round on selection", so a selected button in a square group turns round, which is why
* the selected rules keep `--group-full` rather than `--group-outer`.
*
* Split button (`<x-split-button>`): the same idea for two halves, on its own corner scale —
* SplitButton*Tokens gives the inner corner 4/4/4/8/12px at rest and *grows* it to 8/12/12/20/20px
* under the finger, the opposite of a connected group, so `--split-inner*` is separate from
* `--group-inner*`. The trailing half turns round and its chevron turns over while its menu is
* open, on M3's standard scheme rather than the expressive springs (the site: "the trailing
* button uses the standard motion scheme, not expressive, when rotating"), and the chevron sits
* a little towards the leading half so the pair reads as one control (`--split-nudge`:
* 1/1/2/3/6px). `--split-icon` is the trailing icon's own size, 22/22/26/38/50px, which the
* icon-button table does not know about.
*
* "Full" here is half the size's height (`--group-full`), never `--md-sys-shape-corner-full`'s
* 9999px. One element mixes full outer corners with small inner ones, and when a box's radii
* add up to more than its side, CSS scales every radius by the same factor: a 9999px corner
* beside an 8px one shrank the 8px one to a hundredth of a pixel, so the inner corners drew
* square.
