/* The download page.
 *
 * Same tokens as account.css and app.css, and a SEPARATE stylesheet for the
 * same reason: this page must paint before any chat machinery exists. Someone
 * arriving to install something should not wait on a model picker.
 *
 * The design job here is narrow and specific: a product that is NOT YET
 * available has to look deliberate rather than broken. A greyed button with no
 * explanation reads as a bug; a card that says plainly what it is, what it will
 * need, and what happens next reads as a company that has its house in order.
 * So the unavailable state keeps the full card — art, name, description, the
 * feature list — and changes only the action.
