Toasts now collect in a bottom-right stack. Error/warning toasts are STICKY —
they stay until dismissed so the user can read, select, and copy them while
troubleshooting (e.g. classifier scan errors); info/success still auto-dismiss
(opts.durationMs:0 forces sticky for any level). Each toast has a × to dismiss
it, a "Clear all" appears when 2+ are stacked, and the message text is
selectable/copyable. alert() maps to a sticky error toast.

There are 76 alert() call sites across the eight tools — three different
ad-hoc error-surfacing patterns (alert, console.error, classifier's own
showToast). Touching every site is a sweep with no judgment payoff:
every alert is "something went wrong, the user should know," which is
exactly what toast at level='error' is for.
Shim is one if-block at the bottom of shared/toast.js. It saves the
native window.alert as window.alertNative (so any truly modal-blocking
call site can opt back in by name), then replaces window.alert with a
function that forwards through window.zddc.toast(msg, 'error'). Effect
is global — every existing alert in every tool becomes a non-blocking,
ARIA-announced (aria-live=assertive) toast that the user can click to
dismiss.
handler/tables.html refreshed by ./build as a side effect (it bakes the
current tables/dist/ into the binary every build).

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.
