## What kind of change does this PR introduce?
UI polish / design system: refreshed button styles, related token
tweaks, and a shared floating-button plate.
Resolves DEPR-652.
## What is the current behavior?
Default, primary, and secondary buttons use older fills, borders, and
hover treatments. Primary still leans on brand scale utilities. Default
fills don’t always read as raised chrome across surfaces, and floating
copy / expand / scroll controls can let busy content show through
translucent fills. Call sites hand-roll `rounded-* bg-background`
wrappers for that.
## What is the new behavior?
Refreshes primary, default, and secondary buttons with medium-weight
labels, subtle shadows and inset edges, and smoother transitions.
Light-mode default buttons use a raised fill with an accent hover state,
primary text is brighter, and inline keyboard shortcuts inherit the
button’s colour.
Adds `FloatingPlate`: an opaque `bg-popover` shell for floating default
buttons (and small clusters). Migrates Studio, Docs-related patterns,
www, and `ui-patterns` floaters onto it so busy content no longer shows
through translucent fills. Positioning, z-index, and hover/focus reveal
stay on the plate’s `className`. Use `rounded="full"` for pills.
Also:
- Moves primary onto semantic `--primary` / `--primary-hover` (with a
light-theme override) instead of brand utility fills
- Tokenises button shadows as `--button-shadow-drop` /
`--button-shadow-raised` / `--button-shadow-default` on the Button base
- Aligns hover direction: darken on light mode, lighten on dark mode for
both default and primary
- Default fill stays opaque `bg-card` in light (occlusion) and
translucent `bg-muted` in dark (adapts to the local surface)
- Documents fills and `FloatingPlate` on the design-system Button page
(with a live example)
- Scales shared radius tokens in Studio and www; medium+ Button sizes
use a proportionally softer radius
- Fixes www nav CTA centering (`lg:inline-flex` instead of `lg:block`)
- Query detail Expand/Collapse wires `aria-expanded` / `aria-controls`

## To test
### Design system
- [Button
page](https://design-system-git-chore-button-styles-supabase.vercel.app/design-system/docs/components/button):
default / primary in light and dark; hover should darken on light,
lighten on dark
- Same page: [Floating over
content](https://design-system-git-chore-button-styles-supabase.vercel.app/design-system/docs/components/button#floating-over-content)
/ [Floating
plate](https://design-system-git-chore-button-styles-supabase.vercel.app/design-system/docs/components/button#floating-plate)

## Problem
Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.
## Solution
- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code
## How to test
As this is just prop renaming, if it builds it's ok

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.
