A file the page sent without a name opens untitled and unchanged, like the
empty start presentation, so the page's next file closed it. Host mode now
records the start presentation (start_for_host) and only the first file
that opens takes its place, as packaging/web/README.md says.
Save As > Save under the presentation's own name changed neither the path
nor the dirty flag, so the Save As page stayed open and a second click sent
the file again. The page now also compares the revision, which every save
bumps.

A same-origin page that frames DeckCraft's web build with ?host=parent
sends a file with deckcraft:open and gets every save back as
deckcraft:save {name, saveAs, bytes} instead of a download, with
deckcraft:ready, deckcraft:dirty and deckcraft:failed, as GridCraft,
WordCraft and PdfCraft do. Without ?host=parent nothing changes.
Save follows the desktop app. Every file from the page opens through
file.adopt like File > Open on the desktop; a presentation sent with a
presentation name keeps that name as its file, so Save (Ctrl+S, the
File tab, the Close prompt or the command palette) writes it back under
that name and format with saveAs: false. Anything else (no name, an
outline, a damaged file opened as a repaired copy, a dropped file) is
untitled, and its first Save is a new <title>.deckcraft with saveAs:
true, as is Save As. Exports and Print are copies (saveAs: false).
Host mode starts with an empty presentation that gives way to the first
file while untouched, &author= signs comments, and the URL flags are
read as whole parameters so a free-text author can't set ?show.

* av1: count repeated-frame outputs as they are added
* hevc: give each slice segment its own entry-point list instead of keeping the copied one's allocation
- presentation.json gets its own 256 MiB inflation limit instead of the 2 GiB
per-entry allowance, and is parsed in place: only a file that needs its
null-number repair is copied.
- A media member that fails decoding or its CRC is charged for the bytes it
inflated, so later members cannot reuse the shared media budget.
- repair() and Presentation::validate() check slide layouts against a set
built once instead of scanning every layout per slide.
