   CaseClear blog — shared stylesheet.
   Same design tokens as the main site (index.html): white ground, soft blue
   glows, dotted grid, Space Grotesk display / IBM Plex Sans body / IBM Plex
   Mono labels. One accent (#2f5fe0). Reused here so the blog reads as the
   same product, not a bolted-on CMS.
