   GrowForgeAI — BLOG   (blog.css)  — rebuilt from scratch
   ---------------------------------------------------------------------
   Minimal, mature, near-monochrome. A sibling of the rest of the site:
   same tokens (design-system.css), same Inter type, same hairline cards,
   one restrained indigo accent. The blog carries a quiet "editorial"
   vibe via readable long-form typography — never a different website.

   All blog markup is scoped under .blog-app, so nothing leaks out.
   Tokens consumed from design-system.css / styles.css:
     --text --text-light --bg --bg-light --card-bg --border --primary
     --primary-rgb --ds-r* --ds-shadow* --ds-t --ds-ease
