/* ==========================================================================
   Kulaktan — Design System
   Inspired by the editorial restraint of international law-firm sites:
   left-aligned layouts, hairline structure, serif headlines + a precise
   grotesk for everything else, one muted accent used sparingly.
   Signature motif: the "redaction bar" — a small solid rectangle standing
   in for a line of concealed text. Bullets, dividers and accents are all
   drawn from this one shape, tying the visual language to the product's
   actual subject: protected, confidential disclosure.
