Struct MathBoldTamper 

pub struct MathBoldTamper;

Mathematical Alphanumeric Symbols tamper — replaces ASCII letters/digits with their U+1D400-block Math Bold counterparts. Both NFKC-normalise back to ASCII, so backends that normalise (Postgres ICU, MySQL utf8mb4_0900_ai_ci, Java/.NET/Python/Go NFKC) execute the original keyword while WAF byte-regex sees U+1D4xx codepoints and misses.

Distinct from bracket_confusable / fullwidth: those use the U+FF00 block. Math Bold lives in U+1D400 — different range, different blocklist coverage gap.
