fix(guides): build OG images for all 504 posts (was 39)

[andrew-bierman]

The bug

apps/guides/package.json build script ran in the wrong order:

"build": "bun run generate-og-images && bun run build-content && next build"

generate-og-images runs first and reads lib/content.ts. But lib/content.ts is itself written by build-content from content/posts/*.mdx. So OG generation saw the stale committed version of lib/content.ts (39 posts) instead of the freshly-built 504-post list.

Visible in the CF Pages build log:

• Build content: Built 504 posts and 29 categories
• OG generation: Done — generated 1 root + 39 post OG images

→ 465 of 504 guides shipped without OG/Twitter images.

The fix

One-line swap: run build-content first, then generate-og-images, then next build.

- "build": "bun run generate-og-images && bun run build-content && next build"
+ "build": "bun run build-content && bun run generate-og-images && next build"

Verified locally

Built 504 posts and 29 categories
Done — generated 1 root + 504 post OG images.

Follow-up

A hardening PR will follow with:

• Test asserting generate-og-images count matches build-content post count
• GH Actions workflow that builds guides + landing on every PR (so we get build signal without relying on CF Pages)
• Lighthouse CI guardrails

Pull request overview

Fixes the Guides app build pipeline so OG image generation runs against the freshly generated lib/content.ts (reflecting all posts) rather than the stale committed version, ensuring every guide gets an OG/Twitter image in static exports.

Changes:

• Reorders apps/guides build script to run build-content before generate-og-images.
• Ensures generate-og-images reads the up-to-date posts list via lib/mdx-static → lib/content.ts.
