/* MarquePeptides — homepage-specific styles, loaded only on the front page.
   Shared chrome (root vars, resets, buttons, announcement, nav, mobile menu, mega-menu)
   lives in main.css, which loads first. The homepage logo height override that used to
   live here (100px) was sized for the old compact square mark — the current wide
   icon+wordmark lockup gets disproportionately wide at that height, so this now just
   matches the shared 60px nav height from main.css instead of overriding it. */
