- the modal's hex views carried a 16-byte ASCII column per row; file data is rarely text and the column halved the room for the two before/after views, so it is gone: `hexImageRows` no longer builds an `ascii` field, `hexImageHtml` no longer emits it and the `.hex-ascii` CSS rule is removed - tests: the hex-row test asserts the field is gone (so it cannot come back silently); README/README_RUS wording updated - SW cache simtrace-analyser-v67 (cosmetic, no version bump)
