 *  READING ROOM VIEW
 *  --------------------------------------------------------------
 *  The Reading Room is a flex column: fixed header + one of two
 *  mode panels (search or read) below it. Both panels must be
 *  scrollable when their content overflows. In a flex column,
 *  `flex:1` alone is not enough — children need `min-height:0`
 *  so they can shrink below their content size, and the scroll
 *  container below them needs `overflow-y:auto`. Without the
 *  `min-height:0` chain, the inner reader-scroll never activates
 *  and long documents cannot be scrolled (Task #42).
