Expose a programmatic dismiss method on DialogProvider that fires the
matching close-* event through the runtime, and use it from the eidos
Dialog demo to make the exit-tinting visible.
Soma:
- DialogProvider.dismissWith('save'|'cancel'|'fail'|'dismiss'|
'dismiss-outside') maps to the corresponding morfo event
(close-save, close-cancel, close-after-fail, close-dismiss,
close-dismiss-outside) and fires runtime.trigger().
- DialogProvider class re-exported from $soma/components/dialog so
consumers can call DialogProvider.get() inside a child component.
Demo (test/eidos/dialog):
- New "Exit tinting by causa" section with three buttons that close
the same dialog via three different events:
Save → close-save → border-top tinted success (240ms hold)
Cancel → close-cancel → border-top tinted neutral (240ms hold)
Fail → close-after-fail → border-top tinted danger (600ms hold)
The 600ms fail hold is sema's family='alert' default — the dialog
stays open longer for the user to register the failure before close.
- Uses a small _dismiss-button.svelte child component that captures
DialogProvider.get() at component init time. The inline onclick
pattern (Dialog.DialogProvider.get()?.dismissWith(...)) doesn't
work from the parent route's scope because Svelte's getContext is
init-time-only — the route is the parent of Dialog.Provider, not
a child. The _dismiss-button is rendered inside Dialog.Content so
its init-time context lookup resolves correctly.
Verification (playwright probe):
save t=144ms lastAction=saved hold=240ms
cancel t=116ms lastAction=cancelled hold=240ms
fail t=117ms lastAction=failed hold=600ms (full alert family)
Smoke 68/68.
