A running header (or any text variable) in a parent-page frame was empty or
wrong on pages whose page number repeats an earlier one: with two sections
that both number from 1 (front matter 1-10, body 1-...), body pages 1-10
showed nothing. The renderer and PDF export passed only the page's name to
the composition cache, which looked the page up as the first page with
that name - in the front matter, before any heading.
CompositionCache::get now takes the absolute page index (None for a story's
own frames) and derives the name for page-number markers from it; the cache
is keyed by index, so two pages with the same name no longer share a
composed header. The renderer and PDF export pass first_page_of_spread + i.
Test: running_header_on_parent_page_with_repeated_page_numbers (pages named
1, 2, 1, 2; the only heading on the third page). Before the fix the third
page's header was empty (0 glyphs); with it, "Epsilon" (7).
Found with an InDesign IDML (a dictionary with two sections and Match
Character Style running headers on its parent page), together with #301.

Vertical is a story property: every frame of a thread is vertical or
horizontal together, a frame threaded onto a story takes its direction,
and frames split off by threading or breaking a thread keep theirs.
Type > Story Direction is type.storyDirection {vertical} (checked in the
menu) for the stories of the text selection or selected frames;
object.textFrameOptions {vertical} and frame.create {vertical} set the
frames' stories. Documents that stored Vertical on the frame open with
each story taking its first frame's direction. IDML StoryOrientation is
read into and written from the story, beside its column direction
(StoryDirection), which stays a separate setting.
Rasters stay below vello_cpu's u16 limits (a 65535-pixel-wide render
panicked inside it), page renders larger than 2^29 pixels decline instead of
allocating, PNG encoding never panics, and the PDF heading tag can't fail.
Both crates deny the panicking lints.

- Edit › Paste Into (⌥⌘V): copied objects (with their stories and images) become the selected
frame's content, clipped by it; Item::is_group / has_nested_items; renderer and PDF draw fill,
clipped content, stroke; IDML nests the items inside the frame both ways (verified in
InDesign 2026) (+ tests)
- Polygon Settings: sides and star inset as engine preferences used by the polygon tools and
frame.create; double-click the Polygon tool (+ test)

- render: damage()/damage_with() — changed items and only the frames whose composition changed
(cache keeps the composition each edit replaced; Cache::composed_for matches a document
version exactly); conservative full repaint for styles, swatches, layers, parents, wrap,
effects and cross-story text (+ tests incl. pixel-identical patch vs full render)
- UI: canvas patches its texture after edits with the view unchanged (0.6 ms vs 22 ms on the
sample when typing); perf harness row for the damage repaint
