Navbar block
Navbar Logo-Center Links Fullscreen Featured
Sticky logo-left bar with a centered four-entry menu, always-visible
fullscreen toggle, large destination grid, and a featured articles rail.
Built with ren-nav, native details/summary,
layout primitives, and progressive enhancement — one landmark, no nested
navigation, no second close chrome.
Menus that open the whole page.
A quiet marketing surface under the sticky bar so the centered links, always-visible toggle, and fullscreen featured composition stay easy to judge while you copy the block.
