## Message

```
editor: Keep deleted gutter markers visible at narrow widths (#64469)

Closes #62923

# Objective

Deleted Git gutter markers collapse into a lens and disappear when the
configured gutter width is narrow relative to the buffer line height.

## Solution

- Clamp the deleted marker's corner radii to the marker quad.
- Keep the existing proportional width calculation for default and
custom gutter widths.
- Restore the width helper and its unit test to their behavior on
`main`.

## Testing

- `cargo build -p zed` passes on macOS with Apple's Metal Toolchain
installed.
- `git diff --check` passes.
- Checked before and after at default width, custom width 1, and custom
width 3 with 15 px and 19 px buffer fonts.
- The deleted marker remains full line height in all six patched cases.
The green added-line strip still follows the configured gutter width.
