Press.Style.Cascade (press v0.1.0)

Builds the styled tree: matches CSS rules against the DOM, resolves the cascade (per property, ordered by origin + specificity + source index), applies inheritance, and resolves units to points — except %, which stays symbolic ({:percent, n}) for Layout to resolve against the actual containing block width it computes. See docs/superpowers/specs/2026-07-24-css-parser-cascade-design.md for the full algorithm.
