Isometric figures

From the bundled isokit reference manuals and example source, previously routed through seek-engine. A live figure uses its own interaction loop; the video adapter replaces that clock with a pure seek(t). Static printable sheets keep their distinct rules in technical-drawing; general React and Next.js guidance stays in react. [isokit, references/craft.md; references/motion.md; original seek-engine ISOMETRIC.md]

Copy the whole templates/isokit subtree to the working project before building a standalone example, keeping its inner kit, scripts, references and examples paths. Generated pages belong in that workspace. The original React examples require absent kit/iso-kit.ts and kit/react/draw.tsx/live.tsx dependencies; their described API is preserved as a source prerequisite, not a bundled implementation. The turning renderer remains beta, and the stress example is not audit-clean. [isokit, example imports; references/kit.md; references/3d.md]

Apply only the routes and checks for the selected job. Read a linked skill's named file from its installed folder when available, or from the linked source. Report an unavailable required reference instead of inventing it. [skill-authoring, DISTRIBUTION.md#composing-skills]
