Draw the rich tooltip without Tailwind

Plan step 36 (actions). <x-rich-tooltip> renders data-md-rich-tooltip
with the bubble's data-md-rich-tooltip-bubble and data-md-side, and
data-md-rich-tooltip-title/-text/-actions on its plain text; no class
list. rich-tooltip.css draws RichTooltipTokens' surface-container,
medium corner, elevation 2, 312px bubble, its corner-to-corner anchor
positioning and its fade, the same shape as tooltip.css.

rich-tooltip.js's leave grace goes from 200ms to M3's 1.5s (ACT-25),
matching tooltip.js. RichTooltipTest is rewritten on the hooks and
ComponentStylesheet.

+ * <x-rich-tooltip>: an M3 rich tooltip, a few lines of context for a control, with an optional
+ * subhead and actions.
+ *
+ * RichTooltipTokens (androidx Compose Material 3, Apache-2.0): surface-container, the medium
+ * corner, elevation 2, 312px wide at most, 16px either side, 12px above the subhead (or the text
+ * when there is none) and 8px below it. Title-small subhead and body-medium text in
+ * on-surface-variant, label-large actions in primary — the actions row pulls itself back to the
+ * text's edge with a negative margin, the trick every text-button row in this package uses
+ * (chip.css, fab-menu.css).
+ *
+ * Placed by CSS anchor positioning on `data-md-side`, corner-to-corner so the 312px bubble has
+ * room to spread past a narrow trigger; `position-try-fallbacks` flips it when the window has no
+ * room, same shape as tooltip.css's plain tooltip. It fades in and out on the fast effects spring,
+ * `allow-discrete` keeping `display` and `overlay` alive for the fade out and `@starting-style`
+ * giving the fade in a start.
+ *
+ * resources/js/rich-tooltip.js shows and hides the bubble and keeps the trigger described with
+ * `aria-describedby` — and, while `persistent`, `aria-haspopup`/`aria-expanded` (ACT-22) — none of
+ * which this stylesheet draws.
