What this is
A Reader-First Library
SharePlane is a public-safe publishing medium for finished artifacts, broad in subject but disciplined in structure.
It makes work readable for people and ingestible for agents by preserving provenance, claim posture, metadata, receipts, and validation.
The current implementation is static HTML/CSS/JS, but the strategic identity is web-first, static-first where possible, human-readable, agent-ingestible, receipt-backed, and validation-backed.
