Wires text-input's aria-describedby to the form-field description div (the BSN hint was rendered but never announced), pins desc-before-error ordering, and switches alert to role=alert for errors vs role=status for info/ok/warning. Composition contract enforced by story play tests (form-field+text-input, alert per variant) run in the WP-01 CI gate. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

/** Atom: alert/message banner — the CIBG Huisstijl "melding"

`.feedback feedback-*` classes: the design system owns surface + icon; we add
|
|
only the icon's a11y label and a content wrapper (`.feedback` is a flex row).
|

Errors are `role="alert"` (assertive — interrupts) since they need immediate
|

attention; other variants stay `role="status"` (polite) so success/info banners
|

don't interrupt what the user is doing. */
