+## Render-blocking CSS
+
+Next.js App Router injects CSS via `<link rel="stylesheet" data-precedence="next">`. Because of the `data-precedence` attribute (React's internal hydration ordering), `beasties` inlines critical CSS but leaves the blocking `<link>` intact — Lighthouse still flags it. Work was reverted.
+
+- [ ] Find a strategy compatible with `data-precedence`:
+  - Option A: run beasties, then patch remaining `<link rel="stylesheet" data-precedence="next">` tags to `media="print" onload="this.media='all'"` + `<noscript>` fallback
+  - Option B: wait for a beasties release that handles `data-precedence`
+  - Option C: accept it — the render-blocking CSS is small and GitHub Pages cache TTL is the bigger bottleneck

-# Updating the CV
-
-The CV source lives in the private repo [`AndSanG/CV_MD`](https://github.com/AndSanG/CV_MD).
-
-The published files are hosted as release assets in [`AndSanG/andsang.github.io`](https://github.com/AndSanG/andsang.github.io) (public).
-
-| Asset | Used for |
-|-------|----------|
-| `cv.md` | Rendered inline in the CV dialog |
-| `cv.pdf` | Download button |
-
-## Workflow
-
-1. Edit `CV_MD` and export/generate the updated `cv.md` and `cv.pdf`
-2. Publish a new release to `andsang.github.io`:
-
-```bash
-gh release create v1.0.1 cv.md cv.pdf \
-  --title "CV" \
-  --notes "Updated CV" \
-  --repo AndSanG/andsang.github.io
-```
-
-Bump the tag (`v1.0.1`, `v1.0.2`, …) with each update.
-
-> Run the command from the directory where your updated files are located.
-> Asset names must stay `cv.md` and `cv.pdf`.
-
-## How it works
-
-GitHub's release asset URLs block browser requests (CORS) when fetching via JavaScript. To bypass this, the Next.js build workflow (`deploy.yml`) is configured to:
-1. Trigger a redeploy automatically whenever a new release is published.
-2. Download `cv.md` from the latest release into the `public/` directory right before running `next build`.
-
-This ensures the generated static site contains the latest `cv.md` at its root, so the site serves the content from its own origin (`/cv.md`) with no CORS issues.
-
-The `cv.pdf` download link points directly to the release asset, which works fine as a normal browser download (CORS only affects `fetch()`, not `<a href>` downloads).
