/* LinkPulse — frosted-glass theme on top of Bootstrap 5.3 (light + dark).
   Glass needs something behind it: a slow mesh of colour blobs (.lp-bg) sits under
   every page. Panels are translucent with backdrop blur, a bright top edge and a
   soft shadow. Opacity is kept high enough for text to stay readable, and there's
   a solid fallback for browsers without backdrop-filter.
   Type: Bricolage Grotesque (headings), Public Sans (text), JetBrains Mono (short
   codes only, because l/I/1 and O/0 must be distinguishable in Base62 codes). */
