8// ── captured SVGs are stageable ──────────────────────────────────────────────
9// Regression: `hyperframes capture` extracts inline SVGs into capture/assets/svgs/
10// (assetDownloader.ts), and the capture manifest advertises them to the agent as
11// `assets/svgs/<name>.svg`, so a frame names one in `asset_candidates` exactly as
12// it names a screenshot. stageAssets only searched capture/{assets,assets/videos,
13// screenshots}, so every captured SVG resolved to nothing — reported as a
14// non-fatal anomaly, and the frame 404'd the logo it had been told to use.
