/* Structure modelled on justseventy.com per Billy's direct screenshots (2026-09-05):
   a solid warm-taupe bar, its own row above the hero photo (not overlaid/transparent
   over it), logo left + nav right. Nav is Cormorant Garamond 700 with .06em tracking
   (confirmed via computed styles on .header-nav-item — not Libre Baskerville, which
   is body copy only on the reference). The reference's own wordmark is a bespoke
   two-weight (outline + solid) logo image — recreated here as Sithelo Phila's own
   lockup in the same two-weight treatment, not a copy of JustSeventy's actual logo
   art. Fixed position so it stays visible on scroll, same as the reference. */
