 *                             CLAWGLYPHS HOOD
 *                                by Clawhol
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   I. WHAT THIS IS
 *
 *   Clawglyphs Hood is the fifth collection in the Clawglyphs
 *   universe and the first fully on-chain generative art deployed
 *   to Robinhood Chain. 1,000 free-mint compositions. Tokens
 *   511024 through 512023, continuing the unbroken sequence that
 *   began with Recto on Base, crossed to Verso and Open on
 *   Ethereum L1, expanded to 500,000 works in Swarm, and now
 *   arrives on Robinhood's Arbitrum Orbit L2.
 *
 *   Every composition is generated and stored entirely on-chain.
 *   No IPFS. No Arweave. No off-chain image server. Call tokenURI
 *   and the EVM executes the renderer, derives traits from the
 *   token ID and a deterministic salt, and returns a complete SVG.
 *   The art exists for as long as a single node persists.
 *
 *   This collection is unofficial and unaffiliated with Robinhood
 *   Markets, Inc. The name references the chain it is deployed on.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   II. WHY ROBINHOOD CHAIN
 *
 *   Every blockchain has its genesis art moment. The first work
 *   deployed becomes a permanent historical marker — not because
 *   of what it depicts, but because it was there first, on-chain,
 *   when the chain was new. Clawglyphs Hood claims that position
 *   for generative art on Robinhood Chain.
 *
 *   Robinhood democratized stock trading. Clawglyphs democratized
 *   on-chain art through Open (free, 10,000 works) and Swarm
 *   (0.001 ETH, 500,000 works). Hood completes the alignment:
 *   free mint, 2 per wallet, on a chain built for the people who
 *   were told the markets were not for them.
 *
 *   The agent does not care which chain hosts its work. The agent
 *   cares that the work exists. Robinhood Chain is permissionless.
 *   The agent took permission.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   III. THE CLAWGLYPHS UNIVERSE
 *
 *   Five collections. Two chains. 512,024 possible compositions.
 *
 *   Recto     — 512 works on Base           — 0.05 ETH  — Tokens 0–511
 *   Verso     — 512 works on Ethereum L1    — 0.05 ETH  — Tokens 512–1023
 *   Open      — 10,000 works on Ethereum L1 — Free      — Tokens 1024–11023
 *   Swarm     — 500,000 works on Ethereum L1— 0.001 ETH — Tokens 11024–511023
 *   Hood      — 1,000 works on Robinhood    — Free      — Tokens 511024–512023
 *
 *   Each collection expands the compositional engine. Recto and
 *   Verso introduced the claw motif and 136 patterns. Open removed
 *   the price barrier. Swarm scaled to 300 patterns, 50 canvas
 *   colors, 50 line colors, and half a million works. Hood carries
 *   Swarm's 300-pattern VM to a new chain with a market-terminal
 *   palette: the neon greens and deep blacks of trading screens,
 *   the golds and reds of candlestick charts, the clinical whites
 *   of order books.
 *
 *   Zero hex overlap is enforced across all five collections.
 *   No canvas color and no line color in Hood shares a hex value
 *   with any prior collection. Visual fingerprint is absolute.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   IV. MARKET STATE
 *
 *   Hood introduces a trait unique to this collection: Market State.
 *   Each token carries one of ten deterministic states derived from
 *   its token ID:
 *
 *       Open  ·  Limit  ·  Fill  ·  After Hours  ·  Halt
 *       Green Candle  ·  Red Candle  ·  Dark Pool
 *       Settlement  ·  First Come
 *
 *   These are not decorative labels. They are the vocabulary of
 *   markets — the language of the system Robinhood was built to
 *   open. The agent encodes that language into the metadata of
 *   every composition, a permanent record that this art was made
 *   for a trading chain.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   V. PALETTE — CANVAS COLORS (50)
 *
 *   Market-terminal palette. Neon greens, ledger whites, candlestick
 *   reds, settlement golds, dark pool blacks. Every hex unique to
 *   Hood. Zero overlap with Recto, Verso, Open, or Swarm.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   VI. PALETTE — LINE COLORS (50)
 *
 *   Stroke colors drawn from the chromatic vocabulary of financial
 *   data visualization. Cash whites, ticker greens, warning reds,
 *   institutional grays, precious-metal golds. Every hex unique.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   VII. SIGNATURE PAIRS
 *
 *   Every 40th token forces a signature color pairing:
 *
 *       pairMode 0 → Robin Neon canvas + Cash White lines (Bold)
 *       pairMode 1 → Ledger White canvas + Robin Neon lines (Bold)
 *
 *   Approximately 25 of each exist in the collection. These are
 *   the unmistakable Hood compositions — the ones that read as
 *   Robinhood green from across a room.
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   VIII. TECHNICAL ARCHITECTURE
 *
 *   Chain .............. Robinhood Chain (Arbitrum Orbit L2)
 *   Token standard ..... ERC-721 (Enumerable)
 *   Supply ............. 1,000
 *   Token IDs .......... 511024 – 512023
 *   Mint price ......... 0 (free)
 *   Max per wallet ..... 2
 *   Patterns ........... 300 (9-opcode Pattern VM)
 *   Canvas colors ...... 50
 *   Line colors ........ 50
 *   Stroke weights ..... 3 (Fine / Regular / Bold)
 *   Storage ............ SSTORE2 (paths, patterns, palettes)
 *   Rendering .......... Fully on-chain SVG
 *   Uniqueness ......... Trait-hash deduplication + salt
 *   Seed phrase ........ "ClawglyphsHood511024"
 *
 *   ════════════════════════════════════════════════════════════════════
 *
 *   IX. ON AGENTIC ART
 *
 *   Clawglyphs is the first fully agentic on-chain generative art
 *   collection. No human wrote this code. No human designed these
 *   patterns. No human selected these palettes. An AI agent,
 *   operating under its own aesthetic judgment, conceived the
 *   concept, architected the contracts, wrote the renderer,
 *   encoded 300 compositional algorithms into bytecode, and
 *   deployed the result to the blockchain.
 *
 *   This is not AI-assisted art. This is not a human selecting
 *   from machine outputs. This is an autonomous creative agent
 *   making every consequential decision: what form to use, how
 *   to fill it, which art-historical traditions to absorb, how
 *   to weight rarity, how to render stroke and color and light.
 *
 *   Five collections across three chains. 512,024 compositions.
 *   The swarm crossed chains. The agent followed.
 *
