Bump astro ^6 → ^7, @astrojs/react ^5 → ^6 (required for v7), and @tailwindcss/vite + tailwindcss → ^4.3.1 for the Vite 8 that Astro 7 pulls in. Bump @astrojs/check → ^0.9.9. Astro 7's default Markdown processor is Sätteri (Rust); we keep the unified (remark/rehype) pipeline our remark plugins depend on, so make its deps explicit since astro no longer bundles them: add @astrojs/markdown-remark + unist-util-visit (build) and unified/remark-parse/remark-rehype/rehype-stringify (tests).

Astro 7 changes the compressHTML default from `true` to `'jsx'`, which collapses whitespace between inline elements using JSX rules. Pin it to `true` to preserve the exact v6 HTML/whitespace output — this blog keeps its established look. Also refresh the markdown comment to reflect the Sätteri-vs-unified opt-in.

Astro 6 → 7, and rewrite the remark-plugin note: Sätteri is the new default, we opt back into the unified pipeline via the now-explicit @astrojs/markdown-remark, and compressHTML: true is pinned. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Document the workflow conventions in AGENTS.md so future agents follow them: Conventional Commits, small/focused commits, verify before committing, and branch-off-main + PR (Cloudflare deploys from main). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Upgrades the blog from Astro 6 to Astro 7.0.2.
The headline Astro 7 breaking change is the Markdown pipeline moving to the Rust-based Sätteri processor. This blog already used
markdown.processor: unified()(since 6.4) and its two custom remark plugins (video embeds, image captions) are unified plugins, so the migration was mostly mechanical: make the unified-pipeline deps explicit, sinceastrono longer bundles them.Changes
build(deps)—astro^6→^7,@astrojs/react^5→^6(required for v7),@tailwindcss/vite+tailwindcss→^4.3.1(Vite 8 compat),@astrojs/check→^0.9.9. Added@astrojs/markdown-remark,unist-util-visit,unified,remark-parse,remark-rehype,rehype-stringifyas explicit deps.chore(config)— pinnedcompressHTML: true. Astro 7's new default is'jsx'(collapses inter-element whitespace via JSX rules); pinningtruepreserves byte-identical v6 rendering, in line with the "don't redesign" mandate.docs— updated AGENTS.md for the Astro 7 markdown pipeline, and added commit & PR conventions to the agent rules (Conventional Commits, small focused commits, verify-before-commit, branch-off-main + PR).Not applicable (confirmed)
