📝 Walkthrough

Walkthrough

Three small updates: source.config.ts switches the MDX code-block light theme to one-light and adds a remarkRemoveMdxComments plugin that strips block-comment MDX expression nodes from the AST. The home page QuickLink type gains an optional external flag that controls whether QuickLinkRow renders ArrowUpRight or ArrowRight. Non-functional comments are added to withBaseUrl in shared.ts.

Changes

MDX build pipeline: theme and comment-stripping plugin

Layer / File(s)	Summary
Code theme and remarkRemoveMdxComments plugin source.config.ts	Light theme changed from github-light-default to one-light. New remarkRemoveMdxComments plugin recursively removes mdxFlowExpression/mdxTextExpression nodes whose value is solely a /* ... */ block comment.

Home page external-link icon

Layer / File(s)	Summary
QuickLink external icon variant src/app/(home)/page.tsx, src/lib/shared.ts	ArrowUpRight added to imports; QuickLink type extended with external?: boolean; Acton toolchain entry marked external: true; QuickLinkRow selects ArrowUpRight vs ArrowRight based on that flag. Non-functional comments added inside withBaseUrl.

Poem

🐇 Hop hop, the light theme changed today,
one-light now brightens the coders' way.
Comments stripped clean from the MDX tree,
And external links get an arrow, you see—
↗️ Up and to the right, oh how fancy!
This bunny approves, most romancey. 🌟
