sdd:fill is the fill token of a sdd:Node — for example a status color resolved through the injectable theme system (spec §5, Tier 2), the same indirection sdd:shape and sdd:style use rather than a hard-coded stylesheet.Copy as claim

sdd:fill joins the node's pinnable-aesthetics group alongside sdd:shape, sdd:at, and sdd:size: unmarked, it is cache — rewritten freely on recompute — and ! on a fill line pins it exactly like those siblings, materializing sdd:pinned on the sdd:fill quad (the same "cache unless annotated" invariant, examples decision 2). On the SVG projection, the token surfaces as an sdd-fill-<token> class alongside the shape class (design spec §3).Copy as claim
