/*
 * NoGuri marketing site — "Calm Slate" on the web.
 *
 * Tokens are lifted from the app, not re-picked: colours from AppColorsLight in
 * lib/shared/colors.dart, spacing/radius/type/motion from lib/shared/tokens.dart.
 * The one thing worth stating out loud, because it is the easiest mistake to
 * make here: the brand teal has two values. #55A8BA is the DARK theme's primary
 * and measures 2.73:1 on white; light surfaces use #177E93 (4.73:1). The build's
 * --check fails on #55A8BA appearing in this file at all.
 *
 * The hero backdrop is a port, not a redraw: the gradient endpoints, the four
 * under-glass blobs and the five cloud placements are the constants in
 * tool/gen_marketing_screenshots.py, so the page and the store screenshots are
 * the same surface by construction.
