## Problem
The dashboard renders all timestamps in the browser's local timezone.
When debugging app issues, users often want to see logs and timestamps
in a different timezone (e.g. their app's deployment region) without
changing their OS clock.
## Fix
- New Timezone submenu in the user-avatar dropdown, sitting next to the
existing Theme picker. Search-as-you-type combobox over the full IANA
catalog plus an Auto detect option.
- Selection persists in localStorage (`supabase-ui-timezone`) and
survives `clearLocalStorage()`. No backend schema change.
- New `lib/datetime.tsx` exposes pure timezone-aware formatters
(`formatDateTime`, `formatDate`, `formatTime`, `formatFromNow`,
`toTimezone`) plus a `TimezoneProvider` and matching React hooks
(`useTimezone`, `useFormatDateTime`, ...). The pure functions take `tz`
explicitly so they're easy to unit test (17 vitest cases covering DST
transitions, multi-tz formatting, unix-micro/Date inputs, invalid-tz
fallback).
- The selected timezone propagates to every existing `<TimestampInfo>`
in Studio via a new `TimestampInfoProvider` context exported from
`ui-patterns`. No per-callsite changes needed for those ~20+ surfaces.
- The `UnifiedLogs` date column migrates off `date-fns` to the new
`useFormatDateTime` hook (the rest of the date-fns callers stay as-is,
since they're either internal range math or non-display).
- `ALL_TIMEZONES` (~600 entries) moves out of `PITR.constants.ts` into a
shared `lib/constants/timezones.ts`. PITR keeps a re-export shim so its
callers don't move. New `TIMEZONES_BY_IANA` dedupes the catalog by
primary IANA name (the original list contains both PDT and PST rows for
`America/Los_Angeles`, etc.) and `findTimezoneByIana` provides reverse
lookup.
- Telemetry: `timezone_picker_clicked` PostHog event with
`previousTimezone`, `nextTimezone`, `isAutoDetected` properties.
Notes for reviewers:
- Bare `dayjs(x).format(...)` calls (~157 files) intentionally still
render in browser-local time. Surfaces opt in by switching to the new
wrappers, so this PR is the abstraction plus logs adoption; broader
migration is a follow-up.
- Two `// prettier-ignore` lines (`apps/studio/pages/_app.tsx`,
`apps/studio/components/interfaces/UnifiedLogs/UnifiedLogs.fields.tsx`)
work around a pre-existing local-tooling issue where
`prettier-plugin-sql-cst` strips angle-bracket type arguments under
certain conditions. Project's pinned prettier (3.8.1) does not strip;
the issue surfaces with a globally-installed prettier. Worth tracking
separately.
- Hydration: `guessLocalTimezone()` and `useLocalStorageQuery` are
client-only. Studio is mostly CSR via the Pages Router, but any SSR'd
`<TimestampInfo>` may briefly render in the server's tz before client
hydration. Existing behavior already had this mismatch with `.local()`;
this PR does not regress it.
- Backend timestamps round-tripped through query params and mutations
stay UTC. The picker is display-only.
## How to test
- Run `pnpm dev:studio`, sign in.
- Open the user avatar dropdown (top right). Hover Timezone.
- Search for "tokyo", pick `(UTC+09:00) Osaka, Sapporo, Tokyo`.
- Open any project, navigate to Logs (e.g. `Project > Logs > Edge
Functions`). Hover a log row's timestamp; the popover should show UTC,
the chosen tz (`Asia/Tokyo`), and the relative time. Visible cell text
should be in JST.
- Visit any page that uses `<TimestampInfo>` (Database > Backups,
Project Pause state, Edge Function details). Same tooltip should reflect
Asia/Tokyo.
- Refresh the page; timezone is still Asia/Tokyo.
- Reopen the picker, choose Auto detect; timestamps revert to browser
local.
- Run `pnpm --filter studio test lib/datetime.test.ts`. 17 tests should
pass.

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.

## Problem
We used to have a `_Shadcn_` suffix for all the shadcn form components
because we also had `formik` form components.
This is not needed anymore.
## Solution
- Remove the suffix
- Update all usages
## 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

## What kind of change does this PR introduce?
UI update
## What is the current behavior?
- The vast majority of projects now have physical backups, not logical
- Physical backups are not downloadable
- But we show a disabled `Download` button for each physical backup
- This button has confusing multi-step instructions about `pg_dump` that
are
[inaccurate](https://supabase.slack.com/archives/C02BJ2239GA/p1771979586829419?thread_ts=1771887878.203199&cid=C02BJ2239GA)
## What is the new behavior?
- We only show the (enabled) `Download` button for logical backups

## Additional context
Support believes removing the button entirely will have less of a burden
than a better tooltip explanation.
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
