## What kind of change does this PR introduce?
Chore.
## What is the current behaviour?
Classic Dark remains available across the shared theme library and
several apps. Studio now supports System, Dark, and Light as its theme
modes, but still carries compatibility paths for Classic Dark.
## What is the new behaviour?
- Removes Classic Dark from shared theme options, application commands,
stylesheets, previews, examples, and replay handling.
- Deletes the Classic Dark and faux Classic Dark stylesheets.
- Removes the now-unused Classic Dark branches from Studio theme colour
controls.
- Migrates `classic-dark` to `dark` so first rendered frame renders Dark
(not Light)

## To test
1. In Studio, open Account Preferences → Appearance. Confirm the
available themes are System, Dark, and Light, and that theme colour
controls still work in each resolved mode.
2. Set the `theme` local storage value to `classic-dark`, then reload
Studio. Confirm it renders as Dark immediately and the stored value
becomes `dark`.
3. Open the theme switcher in Design System, Learn, and UI Library.
Confirm Classic Dark is no longer available and Light, Dark, and System
still apply correctly.

## What kind of change does this PR introduce?
This is a first draft at introducing semantic colours to our
Observability charts. This moves away from just random colours being
assigned to prop after prop. They're only scoped to the Database reports
right now, but if it flows nice, we can open it up to the other reports
too.
This also aims to tone down some of the harsher colours in our charts,
such as the orange which sometimes can look like a warning metric/prop.

## What kind of change does this PR introduce?
Chore
## What is the current behavior?
Design system still uses the old CustomFont family, so documented
components no longer match Studio, www, and docs after the Inter /
Manrope rollout.
## What is the new behavior?
Design system uses the same font stack as the other apps:
- Inter for body (`--font-sans`)
- Manrope for headings (`--font-heading`)
- Source Code Pro for mono
Also adopts the Inter-optimised type scale and base weight (`450`) used
in Studio.
## Additional context
Based on Francesco's unshipped `chore/update-fonts` draft (design-system
slice only). Related shipped work: #47306, #47227.

## Summary by CodeRabbit
* **Style**
* Updated the design system with refreshed typography using Inter and
Manrope, with Source Code Pro for code.
* Refined theme typography and spacing tokens, including a more complete
text scale, updated font weights, and container sizing.
* Improved heading styling and ensured `code`/`pre`/`kbd`/`samp` use
consistent monospace treatment.
* Adjusted default border styling and improved font loading/fallback
behavior for more consistent rendering.

This PR migrates all tailwind configs in the apps to be CSS configs.
They import a shared CSS Tailwind config from the `config` package
(which in turns imports the old JS config).
The shared JS config will be migrated to CSS in a followup PR.
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **Chores**
* Centralized Tailwind into a config-driven entrypoint and updated the
app build flow to use the new build step; many apps now import unified
global styles.
* **Style**
* Migrated global styles to a Tailwind v4-style setup, added
project-wide content scanning, consolidated theme imports, standardized
theme tokens (including new --container-site max-width), and added a
small prose utility to remove paragraph margins.

## What kind of change does this PR introduce?
Feature and design-system cleanup. Resolves DEPR-551.
## What is the current behavior?
Admonition supports several overlapping content shapes, but it
previously did not support a first-class success state or
description-only usage cleanly. Title-only usage was also possible,
which made some callouts read like floating headings without body copy.
Docs MDX Admonitions could also pick up prose spacing around rich
children, while the design-system Tailwind config emitted an
ESM/CommonJS warning in the design-system app.
## What is the new behavior?
Adds a `success` Admonition type, description-only support, and a
stricter content contract: `title` or legacy `label` now requires either
`description` or `children`. Existing title-only Studio callsites have
been converted to description-only callouts.
The design-system docs now include examples for description-only and
success Admonitions, plus guidance for `title`, `description`,
`children`, and legacy `label` usage.
This also tightens Admonition body spacing so rich MDX children keep
docs link/code styling without inheriting excessive prose margins, and
renames the design-system Tailwind config to `tailwind.config.cjs` so it
matches its CommonJS syntax.
Warning and destructive alerts now explicitly set `text-foreground`,
preventing nested Admonition titles from inheriting muted
form-description colour after the Tailwind v4 cascade changes.

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.

This PR preps the monorepo for a migration to Tailwind v4:
- Bump all Tailwind dependencies and libraries to the latest possible
version, while still compatible with Tailwind 3.
- Cleans up obsolete Tailwind 3 specific options and configs.
- Cleans up unused CSS files and fixes the CSS imports.
- Migrates all `important` uses in `@apply` lines to using the `!`
prefix.
- Move `typography.css` to the `config` package and import it from the
apps.
- Migrated all occurrences of `flex-grow`, `flex-shrink`,
`overflow-clip` and `overflow-ellipsis` since they're deprecated and
will be removed in Tailwind 4.
- Make the default theme object typesafe in the `ui` package.
- Migrate all `bg-opacity`, `border-opacity`, `ring-opacity` and
`divider-opacity` to the new format where they're declared as part of
the property color.
- Bump and unify all imports of `postcss` dependency.
