Align JudgmentKit’s header with Surfaces

[mikeylong]

Replace JudgmentKit’s ecosystem dropdown with a direct surfaces.systems link and align the shared header layout with Surfaces. JudgmentKit keeps its own favicon logomark and all six navigation destinations.

The header now shares Surfaces’ 72 px height, gutters, Inter typography, mark placement, and link baseline. The mobile menu retains keyboard operation and dismiss behavior; active links keep their width, and the header remains aligned while scrolling and returning through browser history. Classic scrollbar space is reserved so shorter pages keep the same alignment.

Validation:

• Site build and static site checks passed on the isolated branch.
• All 14 header browser cases passed across seven widths in light and dark modes, including favicon loading, menu operation, sticky positioning, navigation alignment, and Back restoration.
• Desktop and mobile comparison with live Surfaces matched the header, shell, mark slot, wordmark baseline, and mobile Menu placement.
• The marketing-pattern assertion now compares background dimensions instead of Chrome’s CSS serialization. The existing main assertion failed locally and in CI on 100% versus the equivalent 100% auto; the updated assertion retains both required layer dimensions and passes desktop/mobile pattern checks.

Restore a visible current state for the home link

When pathName is /, the renderer assigns aria-current="page" only to the brand identifier, but this changed rule applies the visible underline solely to links inside .surfaces-navigation-sections; consequently, the home link looks identical on the homepage and every other page. This violates the visible current-page-state contract in specs/site-header.md; include the identifier in a width-stable active-state rule and cover its rendered style in the browser test.
