Layer Theme

Framework-owned semantic z-index floors that divide global stacking into architectural airspace rather than providing general-purpose tokens. Ordinary content and theme composition normally use document order, local stacking contexts, or explicit values below the persistent floor (currently 0–99). Consuming a system floor assigns interface to that QP-managed stratum; CSS behavior such as position: sticky does not do so by itself. The gaps between floors allow small local adjustments within an assigned stratum without crossing into another one. Enum values are authored vocabulary; System values are framework-owned truths; Roots are independent semantic theme decisions. Derived and Inherited variables remain available through Theme search and linked variable families.
