/*
 * PamperHive website — the whole stylesheet.
 *
 * Self-contained on purpose. PRIVACY.md says there is no analytics SDK and no
 * third-party tracking; a webfont from a CDN or a hosted stylesheet would send
 * every visitor's IP address to somebody else and make that document false. So:
 * system fonts, one file, no imports.
 *
 * Colours are the app's provisional design tokens
 * (shared/.../designsystem/Tokens.kt) so the site and the app do not look like
 * two products. They are provisional there and provisional here — 07-DESIGN-PASS-2.
