What happened

The same drawing (annotations made in another editor, page /Rotate 90) showed two text box problems:

1. Rotated labels. Text boxes turned by 90 degrees (/Rotate 270 on the annotation, the rotation in the appearance /Matrix) were drawn wide and short with clipped text instead of tall and narrow. tekstvakMaat worked out width and height from the /Rect in PDF coordinates while the angle is a display angle; on a /Rotate 90 or 270 page those axes are swapped. Files saved by Open PDF Studio hid this, because their appearance has a single re that is read directly; this producer writes two.
2. Typewriter text. Title-block fields are /IT /FreeTextTypewriter, which never wraps. The app wrapped them like ordinary text boxes. The producer makes the box exactly as wide as the text, so a measurement 0.005 pt wider broke a two-word name onto two lines over the next field (on a PC without the font, more fields broke or overflowed). Saving then wrote the wrap into the file and dropped /IT.

What this changes

• js/pdf/loader/tekstvak-rotatie.js: the size comes from the box as displayed (rectVp), without rounding; an orientation check for the appearance rectangle, with guards (callouts, near 45 degrees, negative or far-off results).
• Typewriter (/IT /FreeTextTypewriter, also the spelling FreeTextTypeWriter): noWrap in the model; the layout breaks only at hard line breaks; the editor uses white-space: pre; the canvas does not clip it.
• Saver: writes /IT /FreeTextTypewriter back and widens /Rect and /BBox to the widest line as other viewers measure it (the larger of the canvas width and the substitute standard font), for left, centred and right alignment; non-standard font names map to a standard font instead of failing.
• js/pdf/saver-test-hooks.mjs lets node tests run the real saver.js.

Unchanged

Text boxes saved by Open PDF Studio itself (including callouts and the /DS margin from 2026.39.2): six own variants on four page rotations save identically except /M, and load to identical models. Ordinary FreeText and callouts from other programs still wrap.

Verification

• 31 new tests plus additions, each seen failing first; npm run test:unit 2629 passed, 0 failed; npx vite build and npm run typecheck green; the changed tests also pass with --no-experimental-strip-types.
• Live check in a local build: the rotated labels are tall and narrow with the right reading direction, the typewriter field stays on one line.
• Save round trip with the full verification set: identical to release 2026.39.2. Text rotation, save duplicates and rotation sweep (46/46) good; comparison sweep: the same flagged files as on main.
• An adversarial review found six defects (ISO spelling, a crash on Helvetica-* font names, centred and right alignment past the box); all fixed test-first.
