ByteTables provides pre-computed 256-entry boolean lookup arrays for byte classification (IDENT_START, IDENT_CONT, WORD, DIGIT, WHITESPACE) and named constants for delimiter bytes (NEWLINE, DASH, DOT, HASH). bench_quick.rb measures parse µs, render µs, and object allocations for the theme benchmark suite.
