Three interrelated studio UX and rendering fixes: 1. Remove the "Ask agent" popup that auto-triggered when clicking large raster elements in the preview. The modal intercepted clicks meant for editable elements and blocked normal selection workflow. 2. Rewrite preview click selection to respect visual stacking order. The previous scoring algorithm weighted DOM depth at 10,000× per level, causing elements inside sub-compositions to beat visually- on-top elements (e.g., clicking Pip Studio selected Sf Chrome instead). The new algorithm trusts elementsFromPoint order and only prefers a deeper candidate when it is a descendant of the current pick — never jumping to an unrelated element painted behind it. 3. Fix manual edits (resize) not surviving video rendering. The producer's seek-reapply script handled translate and rotation but was missing box-size (width/height) reapplication after each GSAP seek. Also added data-hf-studio-box-size to the detection list in htmlCompiler so the script is injected for resize-only edits.
