/*
 * Passmark website (issue #31): the app's evening-sea look. The same still scene as the app (white cliffs, a
 * lighthouse and a ferry at sunset, /scene.svg) behind every page, dark glass under all text, the app's colour tokens
 * and Plus Jakarta Sans. One look, whatever the device is set to. Nothing moves: no animation, no transitions.
 * Text never sits straight on the scene: on wide screens the bright sunset is behind the middle of the page, so
 * every text block is on glass (tests/look.test.ts checks 4.5:1 over the brightest part of the scene).
