   The floating control bar (reset, aspect toggles, settings, help) and the
   two modals (settings, keyboard help). Client-side: controls that only
   show/hide existing SVG elements work fully; controls that would change the
   calculation (house system, zodiac, theme) need a re-render and are shown
   disabled with an honest explanation.
