// Leader/technique modeled (NOT claimed to BE): Microsoft Holograph (spatiotemporal
// data above/below the display plane) + TSL-era particle attractors. We render the ONE
// closed circulation loop as a 3D organ-flow: a beat particle travels a torus ring,
// three YARQA organs (WAQAYCHAQ guard/store · KAMAY act/animate · RIKUY observe) pulse
// when flowing, a work-credit reservoir fills, the last receipt id tickers, and an Ayni
// reciprocity scale balances intake == output == stored (reciprocal, NEVER net-positive).
//
// EVERY value on screen is read live from /api/a11oy/v1/anatomy/loop (doctrine v11:
// WIRE TO LIVE DATA, never fabricate). HONESTY, baked in:
//   - organs are EXPERIMENTAL tier — they carry the BEAT (work + receipts), NOT electrons;
//     never claimed proven.
//   - joules off-box are SAMPLE (no power meter wired). Label read straight from the JSON.
//   - Ayni is reciprocal, never net-positive (no free energy / over-unity).
//   - Λ = Conjecture 1, never a theorem.
//   - when the loop is degraded:true / gpu sleeping, we render the honest DEGRADED state.
// The honesty token for the loop is SAMPLE (joules_label) — surfaced via the live badge
// and 3D billboards. The STRUCTURAL-ONLY chip remains in the legend so all 4 doctrine
// states are visible.
