The frontend reads the main navigation from the headless initial-data type (?type=834, field navigation) in both SSR and SPA mode, has no language switch and keeps its favicons static, so the three page-level fields were dead weight (about 15 kB per page for mainNavigation alone). Removed from page.10.fields; lib.mainNavigation dropped, FaviconsJsonRenderer stays in the code base unused. Verified on DEV: page JSON of /, /product/aligo and /products/appliances without the three keys, footerMenu/metaMenu unchanged, /_json/?type=834 still delivers the 7 top-level items.
