## Problem
The pipeline wizard in #49243 needs publication, initial sync and
replication settings together on its data step.
## Solution
Compose `PipelineDataSection` from the existing controls and use it in
preview-enabled creation. It includes the publication selector,
initial-sync controls and data advanced settings, including BigQuery
table layout.
This preserves the grouping from #51570. Preview off and editing keep
the existing layout. Validation and creation behaviour stay the same; no
wizard routing is added. Stacked on #51570.
## Review instructions
1. Open the [Pipelines
preview](https://studio-staging-git-dnywh-featpipeline-data-section-supabase.vercel.app/dashboard/project/_/database/pipelines),
select a test project with Pipelines enabled and go to **Database →
Pipelines**. Enable **Pipeline creation wizard** in Feature Previews,
then click **Add pipeline**. Confirm **Data** follows **Destination
connection**, with publication and initial sync above its **Advanced
settings**.
2. Select a publication and change the initial-sync option. For
selected-table options, confirm the publication tables are available.
Click **New publication** in the publication selector and confirm the
existing creation panel opens, then cancel it.
3. Expand **Advanced settings** under **Data**. Confirm replication
settings appear, plus table layout for BigQuery, without connection pool
size, staleness or role. Change **Batch wait time**, collapse and reopen
the accordion, and confirm the value remains. Check desktop and phone
widths. Cancel and discard changes; no credentials or pipeline creation
are needed.
4. Turn the preview off and reopen **Add pipeline**. Confirm the
original layout remains. With the preview on, edit an existing pipeline
and confirm its original layout also remains.
## Problem
The pipeline wizard in #49243 needs connection settings before table
selection.
## Solution
With **Pipeline creation wizard** enabled, rearrange the creation sheet
into destination selection, **Destination connection**, then **Data**.
Group name, region, credentials and connection advanced settings
together. Keep publication, initial sync, replication settings and
BigQuery table layout in the data section.
Preview off and editing keep the existing layout. Validation and
creation behaviour stay the same. This still uses the sheet; no wizard
routing is added. Stacked on #51568.

## Review instructions
1. Open the [Pipelines
preview](https://studio-staging-git-dnywh-featpipeline-connectio-6d0876-supabase.vercel.app/dashboard/project/_/database/pipelines),
select a test project with Pipelines enabled and click **Add pipeline**.
Enable **Pipeline creation wizard** in Feature Previews, then reopen the
sheet. Confirm the order is destination cards → connection → data.
2. With BigQuery selected, expand **Advanced settings** under
**Destination connection**. Confirm it contains pool size and staleness.
Expand **Advanced settings** under **Data** below publication and
initial sync. Confirm it contains replication settings and table layout,
without duplicate connection fields. Change a value and collapse/reopen
the accordion; confirm it remains.
3. If available, select DuckLake or Snowflake. Confirm their connection
accordion contains **Pool size** or **Role**, respectively. ClickHouse
and Analytics Bucket have no connection accordion. Check desktop and
phone widths. Cancel and discard changes; no credentials or pipeline
creation are needed.
4. Turn the preview off and reopen **Add pipeline**. Confirm the
original layout returns. With the preview on, edit an existing pipeline
and confirm it also keeps the original layout.
## Problem
The pipeline creation wizard in #49243 needs a destination selection
step that can be reviewed before wizard routing lands.
## Solution
Add `PipelineDestinationSelection` with BigQuery, DuckLake, Snowflake,
ClickHouse and deprecated Analytics Bucket radio options, using Studio’s
existing destination logos. Show it in the creation sheet only when
**Pipeline creation wizard** is enabled in Feature Previews and allowed
by ConfigCat. Preview off and editing retain the existing dropdown.
This is an incremental preview: creation still uses the sheet. No wizard
routing or design-system changes are included.

## Review instructions
1. Open the [preview to Database →
Pipelines](https://studio-staging-git-dnywh-featpipeline-destinati-54dc7d-supabase.vercel.app/dashboard/project/_/database/pipelines),
select a test project with Pipelines enabled and click **Add pipeline**.
With **Pipeline creation wizard** off, confirm the existing destination
dropdown appears.
2. Close the sheet, enable **Pipeline creation wizard** in Feature
Previews and reopen **Add pipeline**. Confirm radio cards replace the
dropdown, with BigQuery selected initially and only destinations
available to your project shown.
3. If Analytics Bucket is available, confirm its card has a
**DEPRECATED** badge. Select it and confirm the bucket fields appear and
the description below says **Destination type cannot be changed after
creation. Analytics Bucket is deprecated.** Click another destination.
Confirm only one card is selected and the connection fields below switch
to that destination. Use arrow keys to move focus and Space to select a
destination. Check at desktop and phone widths. Cancel and discard
changes; no credentials or pipeline creation are needed.
4. With the preview still on, open an existing pipeline for editing.
Confirm its destination dropdown remains locked. Turn the preview off
and reopen **Add pipeline** to confirm the original dropdown returns.
