## Summary
The homepage instance diagram looks visually off when a project has read
replicas — see
[FE-3390](https://linear.app/supabase/issue/FE-3390/adjust-homepage-diagram-spacing-for-read-replicas).
Root cause: the dagre layout in `InstanceConfiguration.utils.ts` was
passing a fake `height: 25` (and a `-70` hack for the load balancer) for
every node, regardless of how tall the rendered node actually is. When
the Primary card grew taller after #45274 added the compute-metrics row,
the gap between the Primary node and the Read Replica node became
visually tight while the gap between the Load Balancer and Primary
stayed loose — the diagram looked lopsided.
## Fix
- Pass the **real measured height** of each node to dagre, sourced from
React Flow's internal measurement (`node.measured.height`).
- Run the layout in two passes:
1. First pass uses small per-type fallback heights so React Flow has
something to render and measure against.
2. Once `useNodesInitialized()` flips true, re-run dagre with the
measured heights and fitView.
- Keep the diagram at `opacity-0` until the measured pass completes, so
the fallback positions are never visible to the user. Subsequent data
refetches don't re-hide the diagram — once measured, it stays visible.
- Drop `NODE_ROW_HEIGHT` and the load-balancer `-70` hack. Replaced with
a small `NODE_HEIGHT_FALLBACKS` table used only on first paint.
- `ranksep` reduced from 160 → 60 since dagre now knows real heights.
Closes FE-3390.
## Test plan
- [x] Open the project homepage for a project with no read replicas —
diagram renders centered, single Primary node.
- [x] Open the project homepage for a project **with** a read replica —
Load Balancer → Primary → Replica spacing is visually balanced; no flash
of fallback positions on initial render; the diagram fades in once.

## Summary by CodeRabbit
* **Improvements**
* More accurate infrastructure diagram layout with better node sizing
and spacing for initial and measured renders.
* Introduced fallback heights so diagrams render correctly on first
paint before measurements are available.
* Region containers now use a consistent fixed height for stable layout.
* Smoother, visually consistent diagram initialization with improved
opacity transition during layout setup.

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
The Primary Database card in the project homepage diagram showed region
and instance size, but no live health data. Users had no quick way to
spot a high-disk or high-CPU situation without navigating to the
database report.
## Fix
Added a clickable metrics row at the bottom of the Primary Database card
showing CPU, Disk, and RAM as percentages, plus active/max connections
when available. Each metric is color-coded (warning at 80%, destructive
at 90%). Clicking the row navigates to the database observability
report.
The metrics are powered by a new \`useComputeMetrics\` hook that wraps
the existing \`useInfraMonitoringAttributesQuery\` and
\`useMaxConnectionsQuery\`, reusing the parse utilities already used by
the database infrastructure section. The \`metricColor\` threshold logic
is extracted into a separate util with unit tests.
## How to test
- Open the project homepage for a running project
- The Primary Database card should show a new bottom row: "CPU X% · Disk
X% · RAM X% · Y/Z conns"
- Values above 80% should appear in amber, above 90% in red
- Click the metrics row and confirm it navigates to
\`/project/<ref>/observability/database\`
- While metrics are loading, a spinner should appear in the row
- If the infra monitoring API is unavailable, the row should show
"Metrics unavailable" instead of zeroes

## Release Notes
* **New Features**
* Infrastructure configuration page now displays real-time compute
metrics (CPU, disk, memory usage) with color-coded usage indicators
based on thresholds.
* Connection information is displayed when available.
* Includes loading states and error handling for metric retrieval.
* **Tests**
* Added test coverage for metric color-coding logic.

## 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

## What kind of change does this PR introduce?
UI nit changes
## What is the current behavior?
- We use big dots `•` to separate semantically different sets of text
that are in the same row
- This looks a bit odd given how large the dot is to text
- We put _Project Settings_ in its own sidebar section but without a
separator like all other sidebar sections
## What is the new behavior?
- Use the smaller dots `·` to separate text
- Place a separator above _Project Settings_ in sidebar

## Context
Just cleaning up the `unifiedReplication` feature flag now that this is
fully rolled out
Also addresses some bugs that I came across while cleaning up,
specifically for the new home page
- Add enabled features flag check for read replicas in database
replication
- Infra diagram, read replicas
- View connection string CTA to open connect UI with the right database
selected
- Replaced all other actions with a "Manage replica" CTA which links to
the replica details page
Feature / Refactor
## What is the current behavior?
Data API docs live at the `/api` route as a standalone page. Old links
point to the previous location.
## What is the new behavior?
Data API docs are moved to the integrations section with a dedicated
docs tab and settings tab. Old links are cleaned up, a mobile menu is
added for data API docs navigation, and minor code review fixes are
applied.
## Additional context
Resolves FE-2517
## Summary by CodeRabbit
* **New Features**
* Revamped API docs UI with reusable section layout, language toggle
(JS/Bash), API key selection, and improved code snippets
* Added Data API docs tab, mobile navigation, and dedicated
loading/error/disabled states
* **Navigation Updates**
* Moved API docs and related links into the Integrations/Data API area
and added redirects to new routes
* Updated various internal links to the new Data API settings and
overview locations
* **Tests**
* Added comprehensive unit tests for Data API utilities
## 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
