The limits on a compressed file's entries were on their lengths. An entry of
one byte at a far offset unpacked everything before it, and each entry behind
the previous one started the stream over and unpacked the JSON and the gap
again: a small hand-made file could ask for hours of decompression. All of it
is now counted against one budget (the entries a writer can make, and the
JSON once more), past which the file is refused as too big.
Save serializes JSON straight into the compressor and writes images from their Arc into the
file; open reads each image into its own buffer, and NodeKind reads its tag first instead of
buffering every node. Already-compressed images are stored rather than deflated again in the
same gzip stream. Limits apply per section, so any file VectorCraft writes opens again. Data
Recovery writes each image once, content-addressed, instead of every interval. Native files open
on a background thread. Files stay readable by main both ways; JSON-only saves are identical.
