Ghostglyph
Unicode ghost inspector: detect, visualize and optionally normalize zero-width, bidi, variation-selector, control and non-printable codepoints in text or model output.
Lab / strange representations
See what ordinary text
tries not to show you.
Reversible puzzles, educational rotor/cube coders and defensive inspection of Unicode/control characters that can become invisible in normal rendering.

Historical rotor/state-machine energy for learning and reversible play, not modern confidentiality.
