+ * Ancient Runic Leather Falcon Hood Bench, Plumage Beak Chape & Raptor Blind Engine for OpenAO MMORPG.
+ * Simulates falconry hood stitching benches and raptor blind shaping blocks (Oak Falcon Hood Bench, Runic Ironwood Falconer Rig, Celestial Void Seraphic Skyhunter Sanctum),
+ * raw tanned shadowhawk plumage leather blanks and gilded brass beak chape sets (Tanned Shadowhawk Plumage Leather Blank, Gilded Brass Beak Chape Set, Celestial Void Starlight Skyhunter Leather),
+ * novice calming blind hoods and seraphic horizon-piercing apex blind recipes (Novice Calming Blind Hood, Master Falconer Plumed Chape Hood, Celestial Void Seraphic Horizon-Piercing Apex Blind),
+ * independent plumage calming soothing & sensory dampening ratings (scaled across catalog baselines ~14% to 100%), calibrated clamped raptor scout vision range bonus and clamped raptor agitated stress mitigation scaling,
+ * upfront leather material deduction on all craft attempts, consistent remainingProvidedLeathers return shapes across all paths, immutable bench cloning for safe rollbacks on both craft and maintain operations, cached static catalog maxima, crypto-secure default gameplay rolls strictly in [0, 1), authoritative catalog power ratio without dead instance fields, and falcon hood bench maintenance.
