The docs build had a fragile implicit dependency on www's filesystem
(`../../../apps/www/public/llms`), flagged by the docs team in #44670.
Rather than formalising that dependency with a shared package, this PR
eliminates it entirely by making www the sole owner of llms content
assembly.
**How it works now:**
`/llms/[slug]` handles all `/llms/*.txt` requests via a 3-step cascade:
1. Dynamic content — `pricing.txt` generated at request time from
`shared-data` imports
2. Local file — product overviews read from `data/llms/`
3. Docs proxy — reference docs (guides, js, dart, etc.) fetched from the
docs app
No hardcoded slug lists, so adding new content just works.
**What changed:**
- `apps/docs/scripts/llms.ts` trimmed to only generate per-source
reference files — www now owns `llms.txt`, `llms-full.txt`, and product
overviews
- Removed `generateLlmsPricing.mjs` build script — pricing generated
dynamically from `shared-data`
- Removed llms rewrites from `rewrites.js` — routes handle everything
with consistent `Cache-Control: public, s-maxage=3600,
stale-while-revalidate=86400`
- Product overview `.txt` files moved from `public/llms/` → `data/llms/`
so all requests go through routes for consistent caching
**Docs team concerns from GROWTH-773:**
| Concern | Resolution |
|---------|-----------|
| Docs build depends on www files at a fragile relative path | Path
removed — docs no longer reads from www |
| www restructuring breaks docs with no obvious connection | Eliminated
— no cross-app filesystem dependency |
| No build order enforcement between www and docs | Not needed — docs
doesn't depend on www's build output |
## To test
- `curl <preview>/llms.txt` — markdown index with doc + product overview
links
- `curl <preview>/llms-full.txt` — combined product overviews + docs
content
- `curl <preview>/llms/pricing.txt` — dynamically generated pricing
tables
- `curl <preview>/llms/auth.txt` — product overview from local file
- `curl <preview>/llms/guides.txt` — proxied from docs app
- `curl <preview>/llms/nonexistent.txt` — 404
- Verify `Cache-Control` header on all responses

## What kind of change does this PR introduce?
- Bug fix that resolves DEPR-396
- Additional improvements to blog post image handling
## What is the current behavior?
Blog post Open Graph metadata often prefers `imgThumb` over `imgSocial`,
so social previews on X, iMessage, and similar surfaces can render the
on-site thumbnail instead of the intended social image.
The image selection and path-normalization rules are also duplicated
across blog surfaces, which makes the precedence rules easy to drift.
## What is the new behavior?
- Centralizes blog image handling in `apps/www/lib/blog-images.ts`
- Uses `imgSocial` first, then `imgThumb`, for blog OG/Twitter metadata
- Uses `imgThumb` first, then `imgSocial`, then the placeholder, for
blog thumbnails and post hero images
- Normalizes relative blog image paths into absolute URLs for metadata
- Adds warning-only validation during content reads/builds for partial
or malformed `imgSocial` / `imgThumb` config
- Updates a few recent blog posts so `imgThumb` is a thumbnail-only
asset instead of duplicating the social image
## Additional context
- Replaces #42319 with the additional above fixes
- Added unit coverage for the shared image helper

This PR removes all CMS code from the `www` app. This includes fetching
of blog posts, API routes for proxying blog posts and types.
All functionality should remain the same (and the number of blog posts
should be the same).
