/* Shared by every version in launch/next: type, colour, the nav, the footer, buttons.
 * Direction (unslop): a companion that learns your days and tells you, straight, whether a change
 * worked. Calm, exact, on your side. A bright morning table: paper, ink, one pen colour (the
 * brand's accent, from brand.js). Moments: the one card that becomes each thing it does; the dot.
 * Signature: the dot. It stands for you, and the story ends with it as the name's full stop.
