/**
 * One column of prompts on a quiet page.
 *
 * Same palette as todo/: everything that is not something you wrote — the
 * connection, the counts, the dates — sits a step back, so the text at full
 * strength is your own. Borders are hairlines at ~9% of the text colour rather
 * than grey, which keeps them quiet in dark mode too.
 *
 * Two controls are drawn louder than the rest, on purpose: the compose box,
 * because catching the idea is why the page is opened on a phone, and the Copy
 * button, because handing it back is why it is opened at the desk.
