/* prytan owner page.
 *
 * Layout: the page is exactly one screen tall (100dvh). The header takes what
 * it needs and <main> gets the rest; nothing on the Cards and Updates views
 * scrolls the page itself. Inside a card the answer buttons stay at the
 * bottom, the image gives up height first, and only the text scrolls. When the
 * screen is wider than tall (a phone on its side, a tablet, a desktop) the
 * image moves to the left and the text and buttons to the right. Sizes use
 * clamp() so they follow the screen between a small phone and a desktop.
