/*
 * HeartGlance marketing site.
 *
 * The palette and type scale are the app's, transcribed from spec/tokens.json, so the site and the
 * product look like the same thing. Atkinson Hyperlegible is the app's family; the "Next" cut used
 * in the apps is not on Google Fonts, and the original is close enough that nobody moving between
 * them will notice a different voice.
 *
 * No JavaScript anywhere, which is why nothing here depends on a scroll listener or a class
 * toggled at runtime.
