… br scan Replace the DOM-scan justified-text.js (PR codedogQBY#686) with a light, cross-platform strategy shared by mobile WebView and desktop foliate: - CSS fallback in @layer readany-justify: body { text-align: justify } is the default, but unlayered book styles always win, so author alignment can never be overridden. :where() keeps specificity at 0. - :where(*:has(> br)) { text-align: start } so direct-br poetry/lyrics lines are not stretched; using :has(> br) (direct child) avoids cascading start onto unrelated siblings of a br-bearing outer container. - Code/tables/captions/forms excluded with text-align: start. - A tiny JS pass reads the computed alignment of only br-bearing block-level elements and pins author-aligned ones (center/right/end, however expressed) inline, so the book's alignment survives our start rule. Pins are tagged and un-pinned on disable (clean undo) or on vertical/fixed layouts. - Vertical/fixed documents are tagged data-readany-vertical (via getDirection on desktop, isVerticalDoc on mobile) so the justify CSS scopes to horizontal text. - justifyBodyText setting retained (default on); when off the layer is not injected.

Summary
Why
Body alignment is currently controlled entirely by each EPUB, so readers cannot request consistent justified prose. This adds that control without overriding content whose layout or alignment is intentional.
