fix(web): Keep canvas zoom out of the detail panel scroll - #68
Merged
Conversation
The window-level wheel handler zoomed the canvas on every scroll, including over the detail panel, so scrolling the chat zoomed the scene instead. Skip zoom for events inside #detail and let the panel and chat scroll natively. Also enlarge the chat (400px panel, 52vh transcript) and give the panel scrollbars a thin dark style matching the page theme.

Scrolling over the open session detail zoomed the canvas instead of scrolling the chat: the window-level wheel handler called preventDefault() on every wheel event, including those bubbling up from #detail and #dChat. The handler now returns early for events inside #detail, so the panel and transcript scroll natively while the canvas keeps zooming everywhere else.
Also makes the chat roomier (400px panel, 52vh transcript with a 140px floor) and styles both scrollbars thin and dark to match the page theme instead of the OS default.
Validated in headless Chromium against a mock session with a long transcript: wheel over chat scrolls with zoom unchanged, wheel over the input leaves zoom alone, wheel over empty canvas still zooms. Scoped suite passes (tests/web-command.test.ts, 28 tests).
