Reposition Posecode as an inspectable movement format

[a-baran-orhan]

What changed

• Repositions Posecode as an inspectable, editable movement format for animation tools, LLMs, and web products
• Replaces the generic marketing hero with a real .posecode source and live 3D render workspace
• Makes LLM authoring an optional path instead of the main product story
• Mirrors the real playground in the landing preview with source state, phase cues, diagnostics, phase ribbon, and transport controls
• Opens the superhero landing from the landing CTAs and as the default playground movement
• Keeps the latest BVH and glTF motion exports, playback speed persistence, product analytics, and locomotion grounding work from main
• Aligns the landing page, product page, playground, specification, movement library, movement pages, and LLM guide around one visual system
• Adds positioning tests so the product story, showcase route, exports, and shared visual tokens do not drift

Why

The previous landing page still read like an AI exercise generator and used a familiar marketing-page composition. The revised design shows the format itself in the first screen and keeps the source beside its rendered result. The landing preview now leads into the same superhero movement and controls users see in the playground.

This branch was also updated with the latest main. Its analytics, export, playback, and grounding changes are preserved in the combined playground.
