Subject: [PATCH] Draw the chips without Tailwind

<x-chip> renders data-md-chip with its type and its states and parts as
data-md-* attributes (elevated, disabled, selected, actionable, the
icon, check slot, avatar, action and remove button), and every colour,
size, target and transition moves into components/chip.css on tokens
(plan step 36). Icons take size 18; the filter checkbox is
md-visually-hidden. chips.js follows the renamed chip hooks.

A disabled filter chip drawn as a label no longer shows a hover state
layer, which M3 never gives a disabled control. Browser tests cover the
32px chip and the remove button's 48px target.

+ * <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
