Local Dev d070730f4a site(theseus.x, ariadne.x): collapse the mobile topnav into a hamburger
Mobile phones were giving the topnav 130 px — three or four wrapped rows —
before the hero even started drawing. On a 375 x 812 viewport that cost
~16% of the first screen to redundant navigation, and the "Get Theseus" /
"Get for Android" CTAs duplicated download buttons that sit in the hero
one scroll away.

The new pattern:
- Desktop (>720 px) is unchanged. Theseus.X drops Brand + Whitepaper from
  the topnav (they live in the deep footer), so the row is now brand +
  Plug-ins + Extensions + Sirius.X + Get Theseus. Ariadne.X keeps the same
  set it had.
- Mobile (<=720 px) collapses to a single ~58 px row: brand on the left,
  a native <details><summary> hamburger on the right, nothing else. The
  dropdown panel is right-anchored, pure HTML+CSS, no JS, keyboard-usable
  via the summary's built-in semantics.
- Theseus dropdown: Plug-ins, Extensions, Sirius.X.
- Ariadne dropdown: Ariadne's Thread, Theseus.X, Sirius.X.

The hero + its primary CTA now fit above the fold on an iPhone 13 class
viewport, which is where this content needs to land first.
