/* #left-col is a flex column where #thread-list (flex:1) is the only
   region that shrinks. Solania stacks two more fixed-height blocks into
   that column — #solania-ad-slot and #solania-footer below — on top of
   core's own header/search/new-chat/footer, none of which core sized
   with this extra chrome in mind. Combined with #left-col's
   overflow:hidden, a short viewport (or core's footer wrapping to a
   second row once "Deleted Chats" appears) squeezes #thread-list toward
   zero instead of the sidebar just scrolling. Give the chat list a floor
   and let the sidebar scroll internally so nothing collapses invisibly. */
