Live testing of the compile-time variable emission surfaced four gaps: - The producer render path never emitted the compile-time stylesheet (only the preview bundler did), so eval-time reads — GSAP .from immediateRender, top-level getComputedStyle — saw undefined vars in rendered output. The producer's inlineSubCompositions now calls the shared emitRootCompositionVariableStyles and passes the variable hooks. - --variables overrides weren't visible at eval time. They now thread from the orchestrator / distributed plan through compileStage into the emitted rules (window.__hfVariables still covers script reads). - Per-declarer rules anchored on data-composition-id, which two inlined instances of one sub-composition share — instance A's rule restyled instance B, and a rule directly on the declarer defeated the host's inherited data-variable-values. Rules now anchor on per-instance data-hf-var-scope markers and layer nearest-host values over declared defaults, mirroring the runtime loader. - Emission ignored authored CSS; a declared default now yields to a var already defined in an authored <style> block (define-if-absent, matching the runtime injection). Also: the figma importer emits background-color (longhand) for solid fills. GSAP backgroundColor tweens cannot read a var() through the background shorthand — its pending-substitution longhands serialize empty, so .from captured nothing and settled on transparent (pre-existing GSAP interaction, reproduced with no composition variables involved). Validated live: eval-time default + override, .from + override, two-instance host branding, authored :root precedence, SDS brand-loop pixel parity.
