## 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?
A11y cleanup follow-up to #47984 /
[DEPR-626](https://linear.app/supabase/issue/DEPR-626).
## What is the current behavior?
Studio had 82 ratcheted `supabase/require-explicit-tabindex` violations
(raw `<button>` / `role="button"` without explicit `tabIndex`).
## What is the new behavior?
- Explicit `tabIndex={0}` (or disabled → `-1`) on those Studio call
sites across nav, `components/ui`, Database, Storage, and the remainder
- Ratchet baseline cleared (**82 → 0**) and the rule **removed from the
Studio ratchet** (debt is gone; ratchet is temporary)
- Rule remains a shared **`warn`** for now — promoting to `error` (and
sweeping www/docs/design-system) is a follow-up
- Also fixed the learn/ui-library call sites that surfaced while
experimenting with error promotion
- Small follow-ups where making controls focusable exposed gaps:
accessible names, disabled/focus consistency, focus-ring polish on
To-test surfaces, home section `KeyboardSensor`, and an E2E locator
tightened after `aria-label="Remove column"`
Prefer migrating to `Button` from `ui` in future touch-ups; this PR
takes the minimal path so Studio debt can stay at zero.
## Additional context
Batches landed together so baseline conflicts stayed simple while
chipping away:
- Hotspots / nav (FirstLevelNav, Marketplace, AttachmentUpload, Column,
Tabs, …)
- `components/ui` shared
- Database + Storage
- Remainder
**Out of scope / intentional deferrals**
- Promoting `supabase/require-explicit-tabindex` to a lint **error**
(follow-up after www/docs/design-system sweeps)
- Tabs/Radio roving, tooltips, context menus, in-menu items
- Full keyboard-accessible tab-close UX (close stays hover +
`tabIndex={-1}`; context menu still closes tabs)
- Data API docs links (`/project/<ref>/api` redirect)
**Reviewer notes**
- Rule only flags raw `<button>` / `role="button"` without a `tabIndex`
prop. `Button` from `ui` already bakes this in
- `tabIndex={-1}` is intentional for disabled controls, in-menu /
roving-focus children, and hover-only tab close
- For dnd-kit grips, put `tabIndex` **after** `{...attributes}` so it
isn’t overwritten (TS2783)
### To test
Use **Safari** with macOS Keyboard navigation **off** (System Settings →
Keyboard). Chrome once for a sanity pass. For each surface below: Tab
until the control is focused, then activate with Enter/Space where
relevant.
1. **API Docs side panel** (Table Editor → open a table → **API docs**)
- Floating API Docs panel — **not** `/project/<ref>/api` (that redirects
to Data API docs; language ToggleGroup uses arrow keys; links are out of
scope)
- Left nav buttons — Tab through several and activate one; active
highlight / navigation still works
2. **Integrations → Marketplace**
- Enable **Integrations layout** feature preview first (avatar menu →
Feature previews)
- `/org/<slug>/integrations` or project integrations marketplace
- “Clear all”, grid/list toggles — Tab + activate
3. **Table Editor → create a table → Columns**
- Drag handles only appear while **creating** (not when editing an
existing table)
- Tab to grip / remove (X) / sensitive-data eye if shown
4. **Project Home** — section drag handles
- Tab to a grip (visible focus ring)
- Optional: Space to pick up, arrows to move, Space/Esc to drop
(KeyboardSensor added)
- Mouse dnd still works
5. **Storage → Policies** — expand/collapse bucket list chevron
(design-system focus ring, no stuck grey open bg)
6. **Support form** (Help → Support) — attachment remove (×) and
add-attachment control when visible
Disabled controls should be **skipped** by Tab.

## Summary by CodeRabbit
* **Accessibility Improvements**
* Improved keyboard navigation throughout Studio by explicitly managing
focus (`tabIndex`) across many interactive controls (menus, tabs,
tables, charts, dialogs, navigation, and form actions).
* Disabled or non-interactive controls are now removed from the tab
order (or made unfocusable), while available actions remain reachable.
* Ensured `type="button"` on relevant controls to prevent unintended
submissions, and refined keyboard focus behavior for various toggles and
copy/remove actions.
* **Chores**
* Updated the ESLint rule baseline configuration to match the new focus
behavior.

## Problem
Now that we migrated all usages of the deprecated `Tabs` component, we
don't need the `_Shadcn_` suffix anymore.
## Solution
Remove `_Shadcn_` suffix from `ui` tabs components. That's all this PR
does, no visual nor functional changes
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **New Features**
* Standardized tab components across the app so pages and dialogs now
use the same consistent tab UI.
* Improved tab-based views in design, docs, studio, learn, and website
experiences for a more uniform interface.
* **Chores**
* Updated shared UI exports to expose tab components directly,
simplifying future usage across the product.

shared theme variables (including OKLCH-based gradients), improving
consistency for charts, code blocks, overlays, icons, and decorative
backgrounds.

styling, reference lines, buttons/badges, sidebar accents, loaders, and
other visual components.

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.
## Summary
Fixes several high-impact Sentry errors reported in production.
### Fixed Issues
- **[SUPABASE-APP-EJ3](https://supabase.sentry.io/issues/7356937474/)**
— `TypeError: Cannot read properties of undefined (reading 'direct')`.
`connectionStringPooler` could be `undefined` when the connection source
doesn't match any key in the connection strings map. Added an early
return guard in `resolveConnectionString`.
- **[SUPABASE-APP-B17](https://supabase.sentry.io/issues/7117468199/)**
— `RangeError: Invalid time zone specified: Etc/Unknown`.
`dayjs.tz.guess()` returns `"Etc/Unknown"` for some users with
misconfigured browser/OS timezones. Added a shared
`guessLocalTimezone()` helper that validates the guessed timezone via
`Intl.DateTimeFormat` and falls back to UTC. Applied across all 4 call
sites.
- **[SUPABASE-APP-BCM](https://supabase.sentry.io/issues/7192934901/)**
— `TypeError: Cannot convert undefined or null to object`.
`Object.entries(definition.properties)` crashed when a JSON schema
definition existed but had no `properties` field. Updated the guard to
check `definition?.properties` instead of just `definition`.
- https://supabase.sentry.io/issues/7357780302/?project=5459134
- https://supabase.sentry.io/issues/7358344652/?project=5459134
- https://supabase.sentry.io/issues/7096737077/?project=5459134
## Test plan
- [ ] Verify connect dialog renders without errors when connection data
is still loading
- [ ] Verify API docs Entity view handles schema definitions without
properties
- [ ] Verify charts/tooltips display correct timezone labels
