/* ThetaCow — the guided flow.
 *
 * DIRECTION: the price is the product, so the number is the hero. One question per screen
 * in large type, one supporting line, and every explanation folded into a disclosure
 * rather than sitting in a paragraph nobody asked for. Warm near-black and cream instead
 * of the blue-black/cyan terminal, with a single persimmon accent.
 *
 * The DOM contract is unchanged: every selector this file styled before it still styles.
 * The flow's markup and its ids are what basic.js binds to, so this is a change of
 * language, not of structure.
 *
 * Fonts are SELF-HOSTED in ./fonts. A page that moves user funds should not make a
 * third-party request on every load — it leaks visitor IPs to Google and makes the app's
 * appearance depend on a host we do not control.
