topic: vcodec

101 modules sharing the vcodec name family (derived from the tree's prefix discipline).

The sovereign video codec lane: encode/decode built first-byte-up, with SIMD kernels measured honestly against end-to-end reality (a 14.6× kernel win that was 1.03× end-to-end taught this lane to benchmark deployments, not functions). Works with the h264 family for interop decode. The playable web delivery rides plain JS + canvas on the served pages — the domain CSP deliberately gates WASM.
