💬 Prompt: We need to display the border radius CSS prop

The top border on left and right is breaking the design https://app.screencast.com/WJXmHnilxEgjC

Lets just display or remove it please

{
.expressive-code .frame, .expressive-code pre {
/* ...

✅ Result: Restored border-radius: var(--smallRadius) on .expressive-code .frame and .expressive-code pre so that regular code blocks retain their rounded corners. Added a more specific rule targeting .expressive-code .frame.is-terminal pre to set border-top-left-radius: 0 and border-top-right-radius: 0 only on terminal-style code blocks. This fixes the visual issue where the pre element's top corners were visibly rounded beneath the figcaption header bar in terminal code boxes, while leaving all other code block styles unaffected.

📝 Walkthrough

Walkthrough

This PR adds a CSS rule override for terminal-styled code blocks in the custom stylesheet. The change targets .expressive-code .frame.is-terminal pre elements to set the top-left and top-right border radii to 0, which removes the rounded corners from the top of terminal code frames while preserving other border-radius values elsewhere.
