bug: explore.html navbar and footer anchors point to sections that do not exist on the page

[ionfwsrijan]

Summary

Every anchor in the explore page's navbar and footer is dead. The mobile menu, navbar, and footer link to section anchors (#home, #how-it-works, #features, #find-project, #the-project, #our-story) but none of those element IDs exist anywhere in explore.html, so clicking them scrolls nowhere.

Evidence

src/templates/explore.html anchor targets (verified lines):

414: <a href="#home" ...>Home</a>
415: <a href="#how-it-works" ...>How It Works</a>
416: <a href="#features" ...>Features</a>
417: <a href="#find-project" ...>Find Project</a>
607: <a href="#home">Home</a>
608: <a href="#how-it-works">How It Works</a>
609: <a href="#features">Features</a>
611: <a href="#the-project">Find Project</a>     # "the-project" id also nonexistent
612: <a href="#find-project">Find Project</a>
630: <a href="#our-story">Our Story</a>
640: <a href="#our-story">About Us</a>

Element IDs present on the page (grep of id="..."): navbar, topic-search-form, topic-search, nav-mobile-toggle, nav-mobile-menu, topic-search-form-mobile, topic-search-mobile, theme-toggle-mobile, explore-filter-form, search, level, interest, time, sort, github-modal-overlay, github-username, github-modal-error, btn-fetch-github, btn-close-github, scroll-top-btn, scroll-btn-icon.

None of the six anchor targets exist. explore.html is a single-page view of the project catalog (filters/search), so these are copied-over homepage anchors that were never removed.

Impact

• All nav and footer navigation on /explore is non-functional — the primary navigation links go nowhere.
• Users landing on the explore page have no working way to jump to sections (they can only scroll).

Suggested Fix

Remove the dead anchors from the explore navbar/footer, or point them at the homepage sections they are meant to reach (e.g. href="/#home"). Add an HTML check so anchor targets without matching IDs fail CI.
