/* =============================================================================
   ultra-solutions.css — design system for /solutions and /solutions/<vertical>

   Written to the same rules as blog/ultra-blog.css and 6options/ultra.css:
   light everywhere, ONE filled-violet element per screen, nothing shouts. The
   reading column earns the attention; the furniture around it stays quiet.

   The icons are stroke-only inline SVG inheriting `currentColor` — the emoji
   they replaced rendered as a different (and on Apple, full-color) glyph on
   every OS, which is why the page read as pasted-together.

   Loaded absolutely (/solutions/ultra-solutions.css) from both the hub and the
   verticals, because /solutions/<id> resolves relative paths one level deeper.
