- Analysis Summary
- Moves syntax coloring for code blocks and plaintext previews to a newer highlighter.
- Why It Matters
- Reliable syntax separation makes long code blocks and attached text files easier to scan.
- Detailed Description
- The experiment compares how language-aware syntax colors are produced in message-editor code blocks and plaintext file previews.
- The default keeps the existing path, variant 1 uses the newer browser-based highlighter, and variant 2 prefers the native highlighter when it is available in the desktop app.
- Current Canary consumers read the setting in code-block editing, plaintext previews, and language selection.
- The confirmed user-facing goal is a more consistent highlighting path; the evidence does not establish a specific color change for every language.
