Component
Navigation
None of the three sites has an extracted, reusable Header/Nav component. All three hand-code header, mobile menu and cookie banner directly inside their own BaseLayout. That's the single biggest shared gap found in the whole audit, worth actually extracting rather than copying by hand again. Switch to Mobile below to compare hamburger behaviour.
Sticky header, gradient CTA pill. Mobile keeps a compact "Get quotes" pill always visible next to the hamburger, rather than hiding the CTA behind the menu.
Adds a live BoE base-rate ticker strip above the header, plus a 3-level text-size control (A / A / A) persisted to localStorage, the only site with one.
Mega-nav pills, one styled gold as "standout" for the Trust Index link. A multi-tab search modal (Peptides / Sellers / Clinics) replaces the plain search box the other two use.
