## What kind of change does this PR introduce?
Studio interface fix.
## What is the current behavior?
Region flags with light backgrounds, such as Japan, can disappear
against light Studio surfaces. Flag rendering is also repeated across
region selectors and infrastructure views.
## What is the new behavior?
Region flags use a shared `RegionFlag` component with the existing small
radius and a subtle 1px border. The treatment is applied consistently
across project creation, replication, read replicas, infrastructure, and
Edge Function observability.

## To test
- Open the new project flow and inspect the selected region and region
menu. Confirm light flags remain visible without changing size or aspect
ratio.
- Open Database Replication and inspect region flags in the diagram and
destination form.
- Open `/project/<ref>/settings/infrastructure` and inspect flags in the
topology, map, and read replica details.
- Open Edge Function observability and inspect the region filter
options.

## Summary by CodeRabbit
* **UI Improvements**
* Standardized region flag displays across project creation,
replication, infrastructure, read replica, and observability views.
* Region flags now use consistent styling, rounded borders, and
rendering throughout the Studio interface.
* Improved visual consistency for selected regions, database nodes,
tooltips, and region options.
* Decorative flags in observability views are handled appropriately for
assistive technologies.

## What kind of change does this PR introduce?
Feature. Stack 4 of 5 for
[PIPE-1007](https://linear.app/supabase/issue/PIPE-1007/move-read-replicas-out-of-replication-into-infrastructure).
Contributes to PIPE-1008.
## What is the current behavior?
Database / Replication lists, creates, and diagrams read replicas
alongside pipelines.
## What is the new behavior?
Replication is pipelines-only. No replica rows, type, or diagram nodes.
`?destinationType=Read+Replica` redirects to Infrastructure. A short
callout points create-mode users at the new home.
## Additional context
Please review, but do not merge until
[#48921](https://github.com/supabase/supabase/pull/48921) is ready to
follow immediately. The flag is already on, so this PR is the
user-facing cutover off Replication.
## To test
`infrastructure:read_replicas` is an enabled-feature, on by default.
There is no Feature Preview or ConfigCat switch. You should already see
the Infrastructure Read replicas section. If you do not, your profile
lists `infrastructure:read_replicas` in `disabled_features`.
Open [Database /
Replication](https://studio-staging-git-danny-pipe-1007-04-cut-from-77ef95-supabase.vercel.app/dashboard/project/_/database/replication?destinationType=Read+Replica).
You should land on Infrastructure with the add-replica sheet, not a
replica destination type. The Replication page itself should be
pipelines-only.

## Summary by CodeRabbit
* **New Features**
* Added guidance directing users to Infrastructure to create read
replicas.
* Added automatic redirection for legacy read-replica links.
* **Updates**
* Replication destinations now focus exclusively on external analytics
and pipeline destinations.
* Updated destination selection, empty states, descriptions, and
diagrams to reflect the streamlined experience.
* Removed read replicas from the replication destination list and
related creation flow.

## What kind of change does this PR introduce?
Bug fix and internal tooling update. Resolves FE-3472.
## What is the current behavior?
Custom Studio icons use inconsistent source stroke widths, and some
child-level styling prevents component props from overriding them. Mixed
custom and Lucide icon sets can therefore appear uneven.
## What is the new behavior?
Custom stroke icons use a root-level `stroke-width="1.5"`; fill-only
logos use `stroke="none"`. The build validates that contract and
regenerated components preserve existing exports and props.
Studio applies the same `1.5` weight across Reports categories and uses
one shared destination icon mapping in the replication selector,
destination rows and diagram.

## Testing
At 100% zoom, compare custom and Lucide icon weight in:
- Reports: **Add your first chart** and **Add block**
- Database > Replication: the destination selector, destination rows and
replication diagram
- Command menu (`⌘K`): **Search Database Tables**, **Search RLS
Policies**, **Search Edge Functions** and **Search Storage**
- Authentication > Users: right-click a user row and compare the
context-menu icons
- Database > Schema Visualizer: open a table node overflow menu
- A paused project: **Export your data > Download backups**

Adds ClickHouse as a replication destination type in Studio.
- New ClickHouse option in the destination type selector, gated behind
the
`etlEnableClickHousePrivateAlpha` organization feature flag (off by
default).
- ClickHouse settings form: URL, user, password (optional), database,
and
- Client-side URL validation requires HTTPS and rejects URLs targeting
internal addresses (loopback, RFC 1918, link-local, CGNAT, IPv6
loopback/link-local/ULA, and IPv4-mapped/NAT64 forms). Server-side
validation remains authoritative.
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
## New Features
- Added **ClickHouse** as a replication destination option (private
alpha), including support in destination selection/panel, replication
diagram rendering, and destination icons.
- Introduced a ClickHouse destination form with fields for URL, user,
optional password (masked toggle), database, and engine selection.
- Added ClickHouse destination config handling for create/update flows,
with normalization and engine support.
## Tests
- Expanded unit tests to cover ClickHouse validation and destination
config building/normalization, including HTTPS-only and blocking
localhost/internal targets.

This PR improves the replication UI in the following ways:
- Adds a new selecion picker for destinations which is split by the
destination location and it's clearer and can scale more when we add
more destinations.
- Adds a much improved section on lag, highlighting new metrics that
could help debug issues more easily.
- Improves the copy across the whole code.
- Fixes the 2d topological view of replication with better status
handling.

## Details of change
Adds Snowflake to the Studio replication destination flow:
- destination selection and display
- create/edit form fields
- validate/create/update payload serialization
- generated Platform API types
Snowflake remains gated behind `etlEnableSnowflakePrivateAlpha`.
**Note:** I have configured `etlEnableSnowflakePrivateAlpha` in
ConfigCat ("all" in staging and tied to my own org id in prod).
## Details of Verification Process
- Studio focused Vitest coverage for form serialization and diagram
mapping
- Studio typecheck
- ESLint on changed Studio replication files
- Local `mise fullstack:dev` smoke test to confirm the Snowflake form
renders ok.

/>
Full create/validate E2E depends on the Platform PR and ETL runtime
rollout.
## Review Requests
Please check the Snowflake wire payload matches the Platform/ETL
contract and that gating/edit/display behavior follows the existing ETL
destination patterns.

## Summary by CodeRabbit
* **New Features**

required/optional fields.
* **Tests**
* Unit tests added for Snowflake form behavior and replication-type
detection.
* **API**
* Destination create/update/validate flows extended to accept Snowflake
payloads.

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
When you have many tables, it's hard to follow the relations between
them in the Schema Visualiser
## Solution
When selecting an edge (the line between tables), highlight it along
with the related tables and columns to make it easier.
Also, if there is enough space, display a popover showing the relation
details
## Screencasts
https://github.com/user-attachments/assets/11d35fa7-3674-4f13-b77f-8ebe25c66b04
## Context
Replaces the provider name with the region code in the infrastructure
settings overview node diagram
- The latter is more important, and we don't really specify the cloud
provider anywhere in the dashboard

/>
Also made the same changes in the upcoming database replication page too
in the form of tooltips
And swapped the title + description to be more consistent (Top: type of
data, bottom: description), same for the table below
