Terminal-Style Code Blocks for Insights

Terminal-Style Code Blocks

Insights article code blocks now render as terminal windows with macOS-style chrome (red/amber/green dots), automatic language labels detected from markdown fence tags, and a copy-to-clipboard button.

• Title bar — three-dot window chrome with language label (bash, TypeScript, JSON, etc.) aligned right
• Copy button — appears on hover in the bottom-right corner, shows “Copied!” confirmation for 2 seconds
• Line wrapping — long lines wrap instead of horizontal scrolling, improving readability on mobile
• Dark terminal background — #0f172a (slate-950) for authentic terminal feel

No changes to existing markdown files required — the terminal chrome is injected automatically from the article template.
