Legibility trials for classical OCR: render text with the built-in font
(ocrclassic.ocr_render_text; font defaults to the model’s font), apply the
capture chain (:func:symrender.capture_degrade, sensor 20000 e / 10 e / 8 bit by
default) with the swept factor (:data:OCR_FACTORS), and read the line with
ocrclassic.ocr_read_line. Each trial draws a fresh sub-pixel offset of the line
and a sensor-noise seed. Outcomes per capture: hit = the whole string read
exactly, misread = at least one character read as a different character
(substituted or inserted, per ocrclassic.ocr_score) — the dangerous case, never
folded into the read rate —, noread = otherwise (rejects ? or missing
characters only). The table has the same columns as :func:symbol_read_trials
(plus rejected_chars / substituted_chars) so :func:symbol_read_pod fits it.
refine and level_jitter work as in :func:symbol_read_trials.
