/* Site shell chrome only. Node styling for the Sheaf-rendered
   surface itself lives in ./sheaf-public/synth-browser.css (verbatim Sheaf
   stylesheet, loaded before this file so these rules can layer on top of
   it without overriding any `#synth-root [data-synth-node-kind=...]` rule).

   Narrow/mobile layout (see index.html's header comment for the full
   trace): this file stacks the shell's OWN chrome -- title above,
   #synth-root, links below -- in plain document flow, which is
   above/below by construction and never beside. That covers everything
   this shell controls; the surface's own internal narrow-vs-wide topology
   is `synth_froggers::FroggersUiSurface`'s own concern
   (app/FroggersUiSurface.hpp, a `synth::ui::SelfSizedSurface`) -- this
   file's rules never need to reflow it, since the surface already builds
   the right tree for whatever width ./viewport-width.mjs reports. */

   non-canvas areas keep the default `touch-action: auto`, so the page still
