## Summary by CodeRabbit
* **New Features**
* Refreshed theming across the UI to use modern color expressions and
shared theme variables (including OKLCH-based gradients), improving
consistency for charts, code blocks, overlays, icons, and decorative
backgrounds.
* **Bug Fixes**
* Improved light/dark color and gradient consistency across axis/grid
styling, reference lines, buttons/badges, sidebar accents, loaders, and
other visual components.
* **Documentation**
* Updated styling/theming guidance to align with the revised semantic
token system and the updated theme variable usage patterns.

## 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

/>
**To test**
- Ensure all existing page types in Studio are un-effected. They
shouldn't be since existing components aren't touched.
- Run design-system and have a read through layout and page header
documentation. Make sure you understand when and where to use the
various combinations of page components and their variants.
**Next**
Once we are happy with these patterns we can gradually start to update
Studio pages that make use of breadcrumbs and/or sub navigation.

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.
