Blink StyleBuilder: The Final Dispatch for CSS Application

These sources provide a technical analysis of StyleBuilder::ApplyProperty, a critical but intentionally minimalist component in the Blink style engine. The function acts as the final dispatch seam between the resolved CSS cascade and the specific mutation of an element's computed style. Key responsibilities include normalizing property identities, handling writing-direction surrogates, and enforcing strict architectural invariants through assertions. The text emphasizes that while StyleBuilder manages the final handoff, the complex logic of parsing and ordering resides upstream in the StyleCascade. Additionally, the documentation highlights how custom properties are handled dynamically through temporary objects and specific validation rules. Ultimately, the sources define the function as a narrow waist in the pipeline that delegates property-specific semantics to generated or handwritten longhand classes.
