/* The Exit Number - the sales page and the gate.

 * The pages either side of the product. Same paperwork language as the memo,
 * same rules from Section 8: no gradients, no rounded pills, no drop shadows,
 * no emoji, no purple.
 *
 * memo.css and app.css are not loaded here. Those live behind the gate with
 * the tool, and neither of these two pages has a memo on it.
