Five fixes:
1. Dialog mobile scroll: DialogContent now has max-h-[calc(100dvh-2rem)]
overflow-y-auto so dialogs that don't fit on screen can scroll
instead of clipping their footer (and Cancel button) off-screen.
2. isDirty false positive: WidgetConfigDialog's SheetForm used
isDirty={draft !== null} which was true the moment you opened edit
mode, even with no changes. Now stores a draftBaseline at startEdit
time and compares JSON.stringify(draft) !== JSON.stringify(baseline).
The discard-confirmation only appears when something actually changed.
3. Mobile edit button always visible: the widget card's edit button was
opacity-0 group-hover:opacity-100 (hover-only). Changed to
md:opacity-0 md:group-hover:opacity-100 — always visible below md,
hover-reveal at md+.
4. Copy button for referenced widgets: WidgetInstanceCard gains an onCopy
prop. On the Dashboard, referenced widgets get a Copy icon button that
triggers detachRef (creates an independent clone). The edit button on
referenced widgets edits the original (shared config).
5. ConfirmDialog Cancel: fixed by #1 (the Cancel button was off-screen
on mobile dialogs that couldn't scroll).
128 tests pass; lint/build green.
