 * The inbox (AB#314): the conversation list, the thread, the composer and notes. Loaded after maluce-pages.css, tokens
 * only, no color literals (a test enforces it). Two panes on a desktop; on a phone one at a time.
 *
 * Text colors here are ink (primary) and ink-secondary. ink-muted is not used: the guide verified it against the
 * page surfaces, not against surface-hover, which a selected row and an outbound bubble sit on.
 * The one hand-tuned radius is the message bubble's 11px, which the brand book allows "only on the bubble".
