Each mark begins on an invisible ellipsoid. Longitude and latitude locate it; a surface normal decides whether it faces us and pushes protrusions outward; projected tangent vectors carry the mark’s local drawing plane through every turn. The face is structural, but the line is allowed to misbehave. Hieroglyphic cats reuse that skull logic with feline ears, slit eyes, whiskers, dense fur noise, geometric collars, sun disks, reeds, and carved picture-mark rhythms. System audio is opt-in: press listen, choose a tab/window/screen, and enable its audio in the browser chooser.
