Spike log showed bubbles ballooning to 3576-5684px (an image loading at natural ~2778px height before
constraint). att-img is capped 240 but some image path wasn't — added .convo-msgs img/.bubble img
max-height:340px as a blanket cap so no message can stretch the thread. Enhanced spike report to name
the tall bubble's img (natural size, rendered height, computed max-height) to confirm.
