/* OBLIQUE — Fashion Editorial.
   White and off-white, warm stone greys, soft black. No cream-spa beige, no rounded pills: square edges, thin rules.
   Type: Archivo (condensed uppercase display, wordmark, prices) · Pretendard (Korean, body) · IBM Plex Mono (captions,
   metadata, placeholder labels). All self-hosted, OFL. Mobile first; one breakpoint (768px) at the bottom.
   The DevTeam demo bar and footer notice keep the shared demo design (fixed colours below, not the brand palette). */
