/* Pepcore storefront – "lab catalogue" design for pepcorepept.store.
   Navy from the Pepcore vial label, electric cyan accent, element-tile cards (each research area has a hue),
   Space Grotesk headings, Manrope text, IBM Plex Mono for data. Light, bright and different from pepcore.net's dark theme. */
