# Objective

Inline code renders as a rounded chip in the Markdown preview (#63118)
but as a square, full-line-height background everywhere else — the agent
panel, editor hover popovers, notifications, and other markdown
surfaces.

## Solution

Inline code with a background color now always renders as a chip with a
4 px corner radius. The radius is fixed at the paint site rather than
exposed through `MarkdownStyle`, so every markdown surface uses the same
rendering without carrying configuration through the element builder and
rendered lines.

Chip backgrounds and text styling remain configurable. Only the corner
radius is fixed, removing the alternative square rendering path and
preventing surfaces from becoming inconsistent.

## Testing

- Updated `test_inline_code_chips_cover_exactly_the_code_span_glyphs` to
cover the fixed chip behavior.
- `cargo test -p markdown
test_inline_code_chips_cover_exactly_the_code_span_glyphs`
- `./script/clippy -p markdown`
