about

nx_synth_serve.nx -- the INTERACTIVE SYNTH STUDIO (all functionality LIVE): one loopback HTTP daemon that serves the studio page + renders on demand. Type a caption -> neural text2motion clip; pick a move -> clip; choose swap slots -> a creature still. Mounted behind the site proxy at /synth. Routes: GET /synth or / -> the studio SPA GET /synth/health -> {"ok":1} POST /synth/api/text2motion body = caption text -> APNG (neural: learned encoder -> class -> tokens) GET /synth/api/move?id=1..6 -> APNG (parametric move) POST /synth/api/variant?sp&hv&ev&tv&build -> PNG still (swap-slot creature, skinned raymarch) Forks per connection (heavy render mmaps reclaimed on child exit). Composes the proven synth organs; nothing new in the render math. license_tier: ORIGINAL
