/* Landing page — "Great Circle" layout, ported from
   docs/superpowers/mockups/great-circle-v2.src.html onto the app's Bond
   Paper tokens (tokens.css: --plane,--bg,--surface,--surface-2,--line,--ink,
   --ink-2,--ink-3,--accent,--accent-2,--up,--warn,--down,--font-mono).
   All classes are `lg-`-prefixed and scoped to this page only (loaded via
   {% block extra_head %} on index.html) so nothing here leaks into, or
   collides with, the shared design system used elsewhere in the app. */
