v0.5.0

New

• Device preview places the rendered page inside an Xteink X3 or X4 body. Choose the body color, compare the native screen dimensions, remap paper and ink tones, or calibrate the reader to its physical size with a 100 mm ruler.
• Every rendered PNG carries its CrossGlyph version in the bottom-right corner, so a shared tuning result says which renderer produced it without changing the simulated framebuffer.
• The Text card folds while keeping its language picker available, leaving more room for the page when the specimen does not need editing.

Fixed

• Per-control comparisons stay set aside when Untuned is switched on and off, including numeric fields, selects, line height, and variable-font axes.
• Reader frames fit narrow and wide layouts without clipping, keep calibrated rulers scrollable at large scales, and repaint only the pixels that changed.
• Rapid redraws cannot let a superseded PNG or error body replace the newer page.
• Pinned optical-size coordinates survive saving and remain visible in variable-font face badges.
