/* ════════════════════════════════════════════════════════════
 * PAGINATION LAYOUT — CRITICAL, DO NOT CHANGE WITHOUT READING
 * ════════════════════════════════════════════════════════════
 *
 * The DOM-based pagination in app.js (findPageEnd / storyOverflows)
 * depends entirely on this layout to produce a #story container with
 * a fixed, known pixel height and overflow:hidden. Here is how it
 * is constructed and why every rule matters:
 *
 * 1. body[data-view="reader"] → height:100vh, overflow:hidden
 *    The body becomes exactly one screen tall with no scrollbar.
 *    This is the foundation — everything else sizes relative to it.
 *
 * 2. #readerView → flex column, height:100vh, overflow:hidden
 *    The reader fills the body. Flex column = toolbar + layout stacked.
 *
 * 3. .controls → flex-shrink:0
 *    Toolbar takes its natural height and does not flex. Remaining
 *    vertical space goes entirely to .reader-layout below it.
 *
 * 4. .reader-layout → flex:1, min-height:0, align-items:stretch
 *    Expands to fill all space below the toolbar.
 *    align-items:stretch makes .reading-col fill the full height.
 *    min-height:0 is required on flex children to allow shrinking
 *    below their content size (browser default is min-height:auto).
 *
 * 5. .reading-col → height:100%, flex column, overflow:hidden
 *    The column between the arrows. Flex column stacks storyHead +
 *    contentView. overflow:hidden clips any residual overflow.
 *
 * 6. #contentView → flex:1, min-height:0, flex column, overflow:hidden
 *    Expands to fill all space below storyHead. Contains #story.
 *
 * 7. .story → flex:1, min-height:0, overflow:hidden  ← KEY
 *    This is the element whose height the pagination measures.
 *    flex:1 gives it all available vertical space in the column.
 *    min-height:0 lets it shrink properly.
 *    overflow:hidden clips content that doesn't fit — visually hiding
 *    any overflow that the pagination measurement detected.
 *
 * HOW storyOverflows() USES THIS:
 *   getBoundingClientRect() on #story gives the exact pixel rectangle
 *   of the visible area. getBoundingClientRect() on the last rendered
 *   word/sentence span gives its actual position. If that element's
 *   bottom > container bottom → vertical overflow (single column).
 *   If that element's left >= container right → horizontal overflow
 *   (3rd CSS column in the 2-column layout below).
 *
 * IF YOU CHANGE THIS LAYOUT:
 *   Any change that alters the computed height of #story will change
 *   where page breaks fall. That is fine as long as the DOM-based
 *   measurement still works (i.e. #story has a non-zero clientHeight
 *   and overflow:hidden). What must NOT happen:
 *   • Do not add overflow:auto/scroll to #story (breaks measurement)
 *   • Do not remove overflow:hidden from #story (content won't clip)
 *   • Do not give #story a fixed pixel height that ignores the viewport
 *   • Do not hide #story's parent before calling renderCurrentPage()

 *   Desktop layout has two columns. The pagination overflow  *
 *   check in storyOverflows() handles this specifically:     *
 *   content that doesn't fit fills a virtual 3rd column to  *
 *   the right, which is clipped by overflow:hidden on        *
 *   .story. The last element in that 3rd column has          *
 *   left >= container.right, which is the overflow signal.  *
 *                                                             *
 * column-fill: auto                                          *
 *   CRITICAL. 'auto' fills column 1 top-to-bottom first,   *
 *   then column 2. 'balance' (browser default) would split  *
 *   content equally between columns, which would change the  *
 *   overflow behavior and break storyOverflows() detection. *
 *                                                             *
 * @media (max-width: 768px) → column-count: 1               *
 *   On mobile there is only one column. Overflow goes        *
 *   downward (vertical), detected by                         *
 *   eRect.bottom > cRect.bottom. storyOverflows() checks    *
