* ci: skip typecheck for scripts-only PRs; fix vercel-ignore empty SHA
Typecheck workflow:
- Add paths-ignore for scripts/** and .github/** on pull_request and push.
Seed scripts are plain .mjs — not TypeScript — so typechecking adds ~2min
with zero coverage benefit for scripts-only changes.
vercel-ignore.sh:
- When VERCEL_GIT_PREVIOUS_SHA is empty or invalid (can happen on incremental
PR pushes), fall back to git merge-base HEAD origin/main instead of defaulting
to exit 1 (build). This was causing Vercel to deploy on scripts-only PRs even
though the ignore script correctly excludes scripts/ from web-relevant paths.
* fix(ci): remove .github/** from typecheck paths-ignore to unblock PR
Previously, every merge to main triggered a Vercel build even for
scripts-only changes (seed scripts, relay updates). Now checks if
any web-relevant files changed on main too, skipping the build when
only scripts/, docs/, .github/, etc. are modified.
Checks VERCEL_GIT_PULL_REQUEST_ID before proceeding.
Branch pushes without an open PR are skipped (exit 0),
eliminating wasted build minutes from 378+ feature branches.
Production (main) always builds.
* feat(blog): add Astro blog at /blog with 16 SEO-optimized posts
Adds a static Astro blog built during Vercel deploy and served at
worldmonitor.app/blog. Includes 16 marketing/SEO posts covering
features, use cases, and comparisons from customer perspectives.
- blog-site/: Astro static site with content collections, RSS, sitemap
- Vercel build pipeline: build:blog builds Astro and copies to public/blog/
- vercel.json: exclude /blog from SPA catch-all rewrite and no-cache headers
- vercel.json: ignoreCommand triggers deploy on blog-site/ changes
- Cache: /blog/_astro/* immutable, blog HTML uses Vercel defaults
* fix(blog): fix markdown lint errors in blog posts
Add blank lines around headings (MD022) and lists (MD032) across
all 16 blog post files to pass markdownlint checks.
* fix(ci): move ignoreCommand to script to stay under 256 char limit
Vercel schema validates ignoreCommand max length at 256 characters.
Move the logic to scripts/vercel-ignore.sh and reference it inline.
* fix(blog): address PR review findings
- Add blog sitemap to robots.txt for SEO discovery
- Use www.worldmonitor.app consistently (canonical domain)
- Clean public/blog/ before copy to prevent stale files
- Use npm ci for hermetic CI builds
* fix(blog): move blog dependency install to postinstall phase
Separates dependency installation from compilation. Blog deps are
now installed during npm install (postinstall hook), not during build.
