# Constrain and Scroll Edit Dialogs and Popups
## Summary
Ensure every edit dialog, form popup, and modal popup remains usable on a viewport that is shorter than its content. Dialog chrome must stay within the visible viewport while the content area scrolls independently.
## Problem
The shared dialog system constrains only components that follow its `dialog-header` / `dialog-body` structure. Several tool-launch and commit dialogs place form content directly inside the container or use a bespoke container, so long forms can be clipped. Existing viewport sizing also relies on `vh`, which is unreliable when mobile browser chrome changes height.
## Scope
- Shared dialog and modal CSS in `apps/web/src/styles/global.css`.
- Mobile notification dropdown sizing in `apps/web/src/styles/utilities.css`.
- Tool-launch and commit popup markup that does not currently provide a scrollable content region.
## Acceptance Criteria
- [ ] Dialogs and modal popups are bounded by the current visible viewport, including mobile dynamic viewport changes.
- [ ] Headers and footer/action bars remain visible while long form content scrolls independently.
- [ ] Tool-launch and commit popups use the shared scrollable content pattern.
- [ ] Mobile sheets, action sheets, and notification dropdowns remain scrollable without propagating scroll gestures to the page.
- [ ] Relevant frontend tests, typecheck, lint, and production build pass.
## Non-Goals
- Redesigning dialog visuals or interaction flows.
- Changing page-level scrolling outside overlays.
