Andreas Reinhold / reiniandClaude Opus 5 52fd65a390 Add InputStylesheetsTest, the inputs twin of the actions stylesheet test
Plan step 36, step 0 of the inputs stream: mirrors ActionStylesheetsTest's
five checks over the seventeen inputs components already rewritten, plus
pagination (its four views live under resources/views/pagination/**, not
components/, so it gets its own small versions of the two view-reading
checks). The "no class list" check also recognises the wrapper fields'
`:class="$attributes->get('class')"` (Blade's own prop-forwarding syntax,
the only way a component with no root element of its own hands the caller's
class to its field) and a `'class' => '…'` attribute-bag entry, and exempts
field.css's week-long autofill transition from the motion-token check.

The new test caught three already-rewritten components writing a bare
`md-visually-hidden` class, which a package view no longer does (only the
three interaction classes, or the caller's own class, reach a view): field's
character-count live region, search's result-count live region, and chip's
native checkbox under a bound filter chip. Fixed by giving each its own
data-md-* hook with the same visually-hidden declarations in its stylesheet,
and chip.css was also missing its `tooltip.css` import for the tooltip
chip.blade.php renders.

/*
* <x-chip>: M3's assist, filter, input and suggestion chips (resources/views/components/chip.blade.php).
*
* From androidx Compose Material 3 (Chip.kt, AssistChipTokens, FilterChipTokens, InputChipTokens,
* SuggestionChipTokens at androidx/androidx 27cf9a7, Apache-2.0): 32px tall, the small corner,
* label-large, 18px icons and a 24px avatar; 16px padding beside a label and 8px beside an icon,
* 8px between (an input chip: 12px, 8px, and 4px beside an avatar). Compose draws the 1px border
* inside the chip; a CSS border takes room, so every padding beside it is 1px short of its token
* (7px for 8, 11px for 12, 15px for 16).
*
* Colours by type and state, each one role (never an opacity but M3's disabled 12% and 38%,
* tokens/state.css):
*
* flat outline-variant border; on-surface ink (assist) or on-surface-variant (the rest);
* the border turns on-surface (assist) or on-surface-variant while keyboard-focused
* elevated surface-container-low at elevation 1, 2 on hover, no border (not for input chips)
* selected a filter chip that is checked or pressed, an input chip marked `data-md-selected`:
* secondary-container with on-secondary-container ink, no border; a flat selected
* filter chip rises to elevation 1 on hover
* disabled on-surface ink at 38%; the border (flat) or the container (elevated, selected) at 12%
*
* Leading icons are primary on assist, suggestion and filter chips; on an input chip they are
* on-surface-variant, primary on a selected chip and while a chip with its own action is hovered,
* focused or pressed (`data-md-actionable`). A trailing icon is primary on assist and suggestion
* chips. A disabled chip's icons take its ink.
*
* The state layer is the chip's own ::before in the chip's ink (an input chip draws it on its
* action, since the remove button is a second control), at M3's hover, focus and press opacities;
* the focus indicator is the package's secondary ring outside the chip. Both the chip (or an input
* chip's action) and the remove button catch presses over 48×48 — M3 lets the target extend beyond
* the visible container. The filter chip's check grows in on the fast spatial spring and fades in
* on the slow effects one; it shrinks on default effects and fades on fast effects, as
* AnimatingChipContent does.
*
* [data-md-chip="assist|filter|input|suggestion"] the chip; data-md-elevated, data-md-disabled,
* data-md-selected, data-md-actionable,
* data-md-icon-start, data-md-icon-end,
* data-md-avatar, data-md-removable
* [data-md-chip-check-slot] a filter chip's check, over its icon when it has one
* [data-md-chip-icon], [data-md-chip-check]
* [data-md-chip-action] an input chip's own button or link (a <span> without one)
* [data-md-chip-avatar], [data-md-chip-icon], [data-md-chip-label]
* [data-md-chip-remove] an input chip's remove button
* [data-md-chip-label], [data-md-chip-icon], [data-md-chip-trailing]
