/* Coven's look for coven.hexwork.co.uk (layout_coven.php), in Hexwork's family: Syne for titles, Geist for text,
   near-black with Hexwork's pink-red (#F0245E) as the one accent, like HexMail, HexOffice, Tally and Pact. Light mode
   comes from the shared tokens (theme.php). The app fills the window like Teams: a rail, the list of conversations,
   the conversation. The one thing that stands out: a message that mentions you carries the accent down its edge.
   Phone first: at narrow widths the list and the conversation take turns and the rail sits along the bottom. */
