/* Śmieciominacz / TrashFlash teaser: one screen, same look as the landing page (landing/landing.css):
   cream paper, ink outlines, hard offset shadows, fraction-colour stripes, amber LCD. Light and flat, no blur.
   Pixelify Sans (OFL, bundled in fonts/) draws capital Z like "2", B like "8" and 5 like "S",
   so it is kept to headings and short labels; buttons and body text use the system font. */
