Task (active — committed 582d1f4, NOT pushed, awaiting creator verification)

Stream widget bounding box: hug the widget on all four sides, pinned to canvas (0,0).

Iterations that failed

1. e917c41 — fixed 1920×1080 viewport + Stretch="Uniform" + startup registration. Failed: Uniform letterboxed the 16:9 canvas into arbitrary‑sized boxes → asymmetric dead padding read as a "gap". Lesson: Fill the box with the cropped frame, never Uniform.
2. 9d4103c — per‑document CSS reset (html/body width/height 100%) + (0,0) anchor. Failed ("enlarged the gap"): forcing dimensions overrode the widget's own layout and expanded the dead space. Lesson: inject only overflow:hidden + transparent background — never set sizes.
3. 8d793af — viewport == element‑box size + Stretch="Fill". Failed (janky / truncating / scrollbars): hosting at the box size clips full‑bleed widgets to their upper‑left chunk, and tracking the box reflows the page on drag. Lesson: render at a fixed canvas size, never track the box.
4. f39ebd9 — crop capture to scrollWidth/scrollHeight bounds + (0,0) + Fill. Partially passed (panel fixes 1a/1b/4 confirmed) but the box stayed loose; the apparent "tight right/bottom" was just the small‑viewport clip edge. ROOT CAUSE: the crop never ran. The script returned JSON.stringify(...) (a string); ExecuteScriptAsync JSON‑encodes every result, so the JSON was double‑encoded → JsonDocument.Parse got a string node → GetProperty threw → try/catch swallowed → bounds unset → no crop. Lesson: return a real JS object, never a stringified one. Also: scroll extents ≠ widget rect (they include page margins).
5. 70fe2b8 — fixed canvas‑size viewport (1920×1080) + crop + Fill. Image render/resize became solid (creator confirmed) but the box still gapped right/bottom and wasn't 0,0. Same silent JSON bug — the crop still never executed — and the measure was scroll extents regardless. Lesson: verify declared mechanics actually execute; assume nothing ran.

Current iteration (web bounding box — UNCOMMITTED, verification pending)

RENDER RESTORED to the last creator-verified-good state (70fe2b8): full-frame capture (no crop), 1920×1080 canvas-size viewport, plain Stretch="Fill". Image rendering is back to "renders and resizes beautifully". The bounding-box dead-space problem is STILL OPEN — do NOT reintroduce any crop until the creator explicitly approves the approach.

Iteration that just failed (a5b9952 — wrapper-excluded content-union crop + image alignment)

Broke the image rendering — creator could not evaluate the box because the image was gone/ruined. Why: the visible-element-union rect is measured ONCE on NavigationCompleted; widget layout isn't settled then (async fonts/images, load animations, iframes), so the crop rect comes out tiny/wrong and the Fill-stretched frame renders a broken/zoomed sliver. This was against the creator's explicit "don't break the rendering" instruction. Lesson: the canvas-size render + Fill is the ONLY verified good base; any crop must be built on it one tested step at a time, never shipped blind.
