   entropyFA — "Signal" site design system
   Navy on ivory, from the Signal brand artwork and the IMPACT 2026 deck.
   Scroll scenes: a .scene is N viewports tall with a sticky .stage inside;
   js/signal.js writes --p (0..1) and toggles .on on [data-at]/[data-only].
   Without JS every scene renders in its final state.
