/* ===== Layout =====
   REDESIGN fix: .project-main used to be a fixed-height, overflow:hidden
   app-shell wrapper — correct for the OLD single 3-column Workspace layout
   (each column scrolls independently), but it also clipped every new
   screen's content (Dashboard/Setup/Review/Export/Tools), which is normal
   flowing page content and needs the page itself to scroll. The fixed-
   height/overflow-hidden behavior now lives on .project-workspace alone,

/* .section-editor's normal min-height:400px (below) exists to give a nearly
   empty section a comfortable click target — but once the header is
   collapsed specifically to free up scrolling/writing space, that same
   fixed floor instead reads as a large dead area below short content,
   fighting the whole point of collapsing. Let it hug its real content
   height in this state instead. */
.editor-header-collapsed .section-editor {
  min-height: 0;

/* The min-height fix above wasn't the dominant cause of the leftover blank
   area — .project-workspace/.editor-area are pinned to a fixed
   calc(100vh - 101px) "independent scrolling pane" height (see below) so
   .editor-wrapper's flex:1 always stretches to fill that full height
   regardless of content, no matter how short the section is. On mobile,
   .chapters-sidebar/.ai-panel are already position:fixed drawers (not part
   of this flex row — see the max-width:992px rules), so nothing else
   depends on .project-workspace's height there; once collapsed, let the
   whole chain size to its actual content instead of the viewport, so short
   sections don't leave a dead area below them. Only the collapsed+mobile
   combination is touched — normal (expanded, or desktop) behavior, and
   long sections that still need to scroll within the collapsed view, are
   unaffected since document/page scrolling takes over instead.

   Selector note: .editor-header-collapsed is toggled on #editorArea
   itself, not on some wrapping element — so .project-workspace (editorArea's
   own PARENT) has to be reached with :has() rather than a descendant
   combinator (".editor-header-collapsed .project-workspace" would never
   match anything, since that asks for a .project-workspace INSIDE a
   .editor-header-collapsed element, the reverse of the real nesting).
   .editor-area itself needs the compound-class form for the same reason
   (".editor-header-collapsed .editor-area" looks for a descendant, but
   editor-area IS the .editor-header-collapsed element). Only
   .editor-wrapper is genuinely a descendant of #editorArea, so the
   descendant form was already correct for it.
