To render syntax-highlighted code blocks with byte-exact copy fidelity, use a dependency-free tokenizer that converts semantic HTML into token spans and runs an integrity probe verifying the rendered text round-trips to the original source, falling back to escaped plain text if the probe fails.

An integrity probe in syntax highlighting verifies that rendered tokenized text round-trips byte-exact to the original source code, preventing silent data corruption during copy and selection so users always paste exactly what was authored.

Add interactive code selection and clipboard copy to semantic HTML by declaring the language once via a class or data attribute, letting the runtime tokenizer automatically generate the per-line gutter, copy-to-clipboard button, and selection model from the markup.

Yes, this syntax highlighting tokenizer works entirely dependency-free by building interactive code chrome features including gutters, copy buttons, and selection models directly from semantic HTML without requiring external libraries or frameworks.

When syntax highlighting encounters an unknown programming language, it applies deliberate fail-soft behavior by falling back to escaped plain text rather than guessing, ensuring the code remains readable and byte-exact without incorrect tokenization.

Theme-safe token palettes keep highlighted code readable when selected by using a 12-role token palette with mandatory light and dark mirrors alongside selection-yield CSS rules, ensuring tokens maintain visual contrast and legibility across themes and active selection states.
