/**
 * Key-value pair form constraints and sanitization patterns.
 *
 * Both regexes target characters dangerous in HTTP-header / env-var contexts:
 *   \x00        – null byte (injection)
 *   \x0A (\n)   – LF  (HTTP header injection / response splitting)
 *   \x0D (\r)   – CR  (HTTP header injection / response splitting)
 *   \x01–\x08, \x0B–\x0C, \x0E–\x1F, \x7F – other C0/DEL control chars
 *
 * KEY_UNSAFE_RE additionally strips TAB (\x09); values keep TAB because it is
 * a valid header-value continuation character per RFC 7230.
