/**
 * One coherent board-infill deck guard laid out along a rail path, as oriented
 * boxes — the AWC Deck Construction Guide (DCA 6) solid-board guard in metres: a
 * 4x4 post at each end (and every bay ≤ 4 ft between), a flat 2x6 cap over them,
 * and a stack of 1x6 boards running flat along the path between the nosing line
 * and the cap, each course held off the one below by a consistent gap. Every
 * member — the cap and every board course — follows the same path and gets a
 * fitting block at a real plan corner, so the courses read as one connected
 * panel that turns cleanly rather than butting open-ended at a corner.
 *
 * It shares the path sampling, corner finding and newel stations in
 * `guard-path.ts` with the baluster and post-and-rail guards, so a straight
 * flight, a chained L/U landing turn, a winder, a curved or spiral sweep and an
 * integrated top landing all read as the same guard; only the sections and the
 * horizontal board infill differ. Pure data — no Three.js, no React.
 *
 * `reach` runs the members that far past the top vertex along the final slope to
 * die into a post standing there; `topPost: false` then omits the top post.
 * `postThrough` runs the posts past the cap with a small cap of their own.
