+ * Cost-disclosure modal shown before activating a priced skill.
+ *
+ * Shows the daily rate and setup fee (each only if > 0) and
+ * requires an explicit Confirm before the activation request goes
+ * through. Rendered every time the user toggles on a priced skill,
+ * not once-and-remember — this is recurring-charge consent, not a
+ * one-time terms agreement.
+ *
+ * The setup fee is always shown when configured, with a note
+ * clarifying it's "one-time, charged on first activation". The
+ * backend (billing.ts tenantSkillHasBeenBilled) is the authority
+ * on whether the fee actually fires — we don't second-guess from
+ * the client. If you've previously activated this skill on this
+ * tenant, the fee won't appear on the next invoice even though
+ * the dialog mentions it.
