Summary

The Grid block currently doesn't support a way to adjust the gap between grid cells. Block spacing (gap) exists and works for Grid, but the control lives under Styles → Dimensions, so it's easy to miss and doesn't match where users look when editing a grid (Layout: columns, rows, minimum column width, etc.).

This issue asks for a Gap width (or equivalent block spacing) control to be exposed in the Layout panel when the selected block is a Grid layout, so gap is adjustable next to other grid options.

Current behavior

• Group block → Layout type: Grid.
• Layout panel shows: layout type (Stack / Row / Grid), Grid item position, Columns (and related grid options). No gap control.
• Block spacing (gap) is under Styles → Dimensions, so users have to leave the Layout context to change gap.

Desired behavior

• When Layout type is Grid, the Layout panel should include a Gap width (or "Block spacing") control (single value and/or row/column split, consistent with other layout blocks).
• Same style.spacing.blockGap attribute and Core layout support; only the placement of the control changes (Layout panel instead of Dimensions for this layout type).

Why this belongs in Core

• Discoverability: For Grid, gap is a layout concern. Users expect to set columns, rows, and gap in one place (Layout), not gap under Dimensions.
• Consistency: Row/Stack and other layout types already surface spacing in the layout flow; Grid is the odd one out.
• Real usage: Grid is used for card layouts, icon grids, etc.; gap is essential and is currently hard to find.
