Thanks @CVEngineer66 — nicely scoped this time (one file, one concern) and the MutationObserver pattern is clean. Merged. Heads-up: |

Summary
Code block syntax highlighting colors now switch together with the app theme (light ↔ dark).
Motivation
The Prism syntax highlighting theme in
CodeView.tsxwas hardcoded with dark-mode-only colors (#dde1eaon dark backgrounds). When switching to light mode (data-theme=light), the code text remained in pale dark-mode colors — nearly invisible on a white background.Changes
desktop/src/CodeView.tsx— Added aLIGHT_THEMEwith GitHub-style light syntax colors alongside the existingDARK_THEME. Added ausePrismTheme()hook that observes<html data-theme>viaMutationObserverand returns the appropriate theme.CodeViewnow passes the dynamic theme to<Highlight>.Only the syntax colors change — the code block background is already handled by CSS variables.
Verification
npm run verifypassesdata-themeattribute changes (no unnecessary re-renders)
