   EarnWhile — website styles
   ==========================================================================

   Every colour, radius and spacing step below is ported directly from the iOS
   app's design system (EarnWhile/Views/Shared/DesignSystem.swift). If a token
   changes there, change it here so the two stay in step.

   The app is deliberately light-only — see docs/DARK_MODE.md — so this site
   commits to the same light palette rather than inventing a dark theme the
   product does not have. Every surface paints its own background explicitly so
   the page never borrows a host theme.

   Motion and micro-interactions
   --------------------------------------------------------------------------

   Rules this layer follows:

   • Only `transform`, `opacity` and `box-shadow` are animated. Nothing here
     touches width, height, margin or padding, so nothing can shift layout.
   • Hover effects are decorative only. Every one of them is additive to a
     state that already reads correctly without it, and none is needed to
     understand or operate the page.
   • Hover lifts sit behind `@media (hover: hover)` so touch devices do not
     get stuck in a hover state after a tap.
   • Scroll-reveal and the bar growth are opt-IN, applied by JavaScript. The
     default stylesheet renders everything in its final state, so with JS off
     or broken the page is complete and nothing is invisible.
   • The reduced-motion block at the end switches all of it off, not merely
     shortens it.
