   scrolls instead of wrapping. */

   The landing page shows the whale over an empty hero, so 0.30 reads well
   there. The platform is wall-to-wall cards at rgba(12,20,40,.65) - anything
   behind them survives at ~35% of its own alpha, so 0.30 became roughly 0.10
   and vanished. These values are what it takes to still be perceptible
   *through* the cards without competing with the numbers on top of them. */
