Force cyberpunk theme on Own your AI

[feynon]

What changed

• Force /blog/own-your-ai to use the cyberpunk theme regardless of the visitor’s saved preference.
• Apply the cyberpunk and dark classes before first paint.
• Keep the theme switcher hidden so cyberpunk is the only available theme on this post.
• Remove the route-specific near-black CSS overrides that suppressed the yellow cyberpunk announcement treatment.
• Update the repository guidance to preserve this route behavior.

Why

The post was locked to the plain dark theme. It also had higher-specificity route styles that overrode the site-wide cyberpunk palette, so changing only the forced theme would not have produced the complete cyberpunk presentation.

Validation

• git diff --check
• Route helper assertions for the exact post path, nested path, and unrelated blog path
• SWC syntax compilation for all edited TypeScript and TSX files
• Development render returned 200 for /blog/own-your-ai
• Verified the server-rendered page applies cyberpunk and dark before first paint
• Verified the server-rendered top bar omits the theme switcher
• Next.js production compilation completed successfully; static generation then stopped on the pre-existing /book/_archived/memory-inference-time prerender error
