Text import turns the gap between an absolutely positioned <tspan y> and the previous line into
that many line breaks, with two problems:
- At least one break was added even when the tspan sits on the current baseline. Styled or
kerned runs written with x and y on every tspan (as Illustrator writes them) were split into one
line per run: "Hello <tspan y=same>world</tspan>" came back as "Hello \nworld".
- The count had no upper bound. A tspan with y="1e15" (or any y far below its text) asked for
~10^14 '\n' characters, and opening the file aborted the app, the MCP server or
`vectorcraft-cli` with "memory allocation failed" after eating all memory.
A tspan less than half a line from the current baseline now adds no break, the gap is capped at
10 000 line breaks, and a non-finite gap counts as one; other gaps are unchanged.
