Design Blueprint: Bamboo Culm Beam Spans, Single and Bundled

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24115123): Bamboo culm beams, single or bundled, spanning only within the deflection-governed bounds in the source paper for the stated loads. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
