/* pitch.css — the /pitch/{client}/ proposal engine.

 * Generic by design: everything client-specific lives in the page content

 * reusable half of the proposal product.
 *
 * Loads after styles.css + admiralty-tokens.css and leans on their tokens:
 * --ink --paper --paper-warm --surface --line --forest --forest-deep
 * --brass --brass-soft --brass-ink --clay --fog --fog-ink --radius --shadow
