/**
 * Emoji Trigger — Quantum State → Emoji Sequence → Opcode Metadata
 *
 * The emoji art IS the program. The metadata IS the instruction set.
 * What looks like decoration to an observer is executable routing data.
 * This is Dee's Monas principle made operational: one glyph = multiple layers.
 *
 * Architecture:
 *   QRNG bytes → emoji pairs (left=type, right=modifier)
 *   Each emoji pair: carries opcode, Abjad weight, BOB route, PLANNER rule
 *   Highest-Abjad pair = primary trigger for this quantum tick
 *   Tessera program auto-generated from the sequence
 *   Full metadata sealed into WORM
 *
 * Why emoji?
 *   1. Steganographic — looks like decoration, is executable
 *   2. Custom per indie group — your emoji map = your instruction set
 *   3. Hard to reverse without the Abjad key
 *   4. Dee's Monas: each symbol encodes multiple simultaneous meanings
 *   5. Entry point to SnapKitty — the art IS the access
