薬草の干し棚

// Herb drying rack — 48x48 WALL prop (no contact shadow), 3/4 view, key light top-left.// A rough-hewn beam held to the wall by two iron straps; six things hang from it on twine wrapped round the beam:// a sage bundle, a garlic braid, a lavender bunch, a dried lizard charm with a blood bead and a rowan-berry sprig. Every bundle hangs upside down: cut stem ends above the tie, sprigs fanning out below.// Each hanging thing is drawn as a pure function of local (pivot) coordinates and swung by a shear about its pivot,// so the whole mass moves and the twine stays attached.// Variants (16f loops @10fps)://   idle    bundles sway gently, each out of phase//   breeze  a gust leans them to the right and they swing harder; a sage leaf and a lavender floret break off and fall//   dried   the same bundles browned and withered (key remap inside the palette), thinner sprigs, barely movingconst W = 48, H = 48, PY = 11;                       // PY: first row under the beam (twine leaves the beam here)const BX0 = 2, BX1 = 45;                             // beam spanlet MODE = "idle";// withered remap: greens go to wood browns, violet greys out, berries shrivel darkconst DRY = { e0: "w0", e1: "w1", e2: "w2", e3: "w3", v0: "w0", v1: "v0", v2: "v1", v3: "n3",  r1: "r0", r2: "r1", r3: "w2" };const K = (k) => (MODE === "dried" && DRY[k]) || k;const ramp4 = (l, a, b, c, d) => K(l > 0.55 ? d : l > 0.05 ? c : l > -0.45 ? b : a);// ---- shared shape helpers (local coords: lx right, ly down from the pivot) ------------------------------------// a fan of sprigs hanging from a tie at ly=T; returns the sprig hit with the smallest |across| (front sprigs win)function fan(lx, ly, F) {  const dy = ly - F.T + 0.5;  if (dy < 0) return null;  const r = Math.hypot(lx, dy), a = Math.atan2(lx, dy);  let best = null;  for (let j = 0; j < F.n; j++) {    const aj = -F.spread + (2 * F.spread * j) / (F.n - 1);    const along = r * Math.cos(a - aj), perp = r * Math.sin(a - aj);    const L = F.len[j] * (MODE === "dried" ? 0.92 : 1);    if (along < 0 || along > L) continue;    const w = F.width(along, L, j) * (MODE === "dried" ? 0.8 : 1);    if (w <= 0.2) continue;    const f = perp / w;    if (Math.abs(f) > 1) continue;    const score = Math.abs(f) + Math.abs(aj) * 0.6;    if (!best || score < best.score) best = { j, d: along, L, f, score, aj };  }  return best;}const sprigPos = (F, j, d) => {  const aj = -F.spread + (2 * F.spread * j) / (F.n - 1);  return [Math.sin(aj) * d, F.T - 0.5 + Math.cos(aj) * d];};// cut stem ends above the tie, and the twine wrap of the tiefunction tieAndStems(lx, ly, T, hw, stemA, stemB) {  if (ly >= T && ly <= T + 1 && Math.abs(lx) <= hw) return K(ly === T ?
