   SurgeonsLab Blogs — shared stylesheet
   Namespace: every selector is prefixed sl-blog- so this can never collide
   with, or be affected by, the legacy site CSS (style.css).
   Powers both /blogs (overview/index) and /blogs/{slug} (single post).
   Brand tokens reused from the main site: Univia Pro / Roboto, #16BBBB cyan,
   #030100 ink, #404040 body grey — kept consistent on purpose.
