Promote classifier's local toast (classifier/css/base.css + showToast
in classifier/js/excel.js) into shared/toast.{js,css}. Every tool's
build.sh now concatenates them, so window.zddc.toast(msg, level, opts)
is callable from any tool.
API:
window.zddc.toast('Saved.', 'success');
window.zddc.toast('Could not load: ' + err.message, 'error');
window.zddc.toast('Note', 'info', { durationMs: 3000 });
Levels: info (default) | success | warning | error. Single-toast
policy — a second call replaces the first. Click anywhere on the
toast to dismiss. ARIA: error → role=alert/aria-live=assertive,
others → role=status/aria-live=polite.
Class prefix is .zddc-toast (BEM-ish) to avoid colliding with any
tool-local .toast rules. Classifier's existing showToast now
delegates to window.zddc.toast — call sites in excel.js +
selection.js are unchanged. Classifier's local .toast CSS block
deleted in favor of the shared one.
This commit only EXPOSES the API. Replacing the ~25 alert() call
sites scattered across archive/transmittal/mdedit/classifier with
toast calls is left as follow-up — each alert needs per-call review
to decide if it's truly non-blocking.
Five Playwright tests in tests/toast.spec.js lock the contract:
API exposure, level mapping, ARIA roles, single-toast replace,
click-to-dismiss.
