 * PillarDetail — Pillar (2021, Alexander Lotersztain). Configure + Endure.
 *
 * A table system built on the Australian cattle-rail extrusion — strong,
 * unyielding, and reframed as the structural backbone of a modular table
 * family. 9 SKUs across 4-leg, 6-leg and 8-leg rectangles, a standing-height
 * 4-leg, and two circles. Variable sizing within each SKU. Indoor only.
 * GECA certified. Made in Australia. Connectivity by OE Elsafe.
