Build a reference page for the form and feedback components of Harbor Bank, a fictional online bank. Designers and engineers at the bank use the page to check how each component looks in each state. Every state listed below must be visible on the page at the same time; seeing a state must not require clicking, typing or waiting.

## Sections and content

1. **Header.** Title "Harbor Bank component states". A one-sentence description: "Form and feedback components, each shown in every state." Navigation links to each section below: Text fields, Choices, Buttons, Transfers list, Messages, Transfer form. On small screens the navigation must still be reachable.

2. **Text fields.** A field labelled "Account number" with the hint "10 digits", shown in these states: default (empty), focused, filled with "4021957310", disabled, read-only, error with the message "Enter a 10-digit account number.", and success with the message "Account verified."

3. **Choices.** Four controls, each shown in the states listed:
   - Checkbox "Send me paper statements": unchecked, checked, focused, disabled, error with the message "Accept the terms to continue."
   - Radio group "Statement frequency" with the options Monthly, Quarterly, Yearly: none selected, one selected, focused, disabled, error with the message "Choose a frequency."
   - Toggle "Notify me of transfers over $500": off, on, focused, disabled.
   - Select "Transfer from" with the options Everyday account, Savings account, Joint account: closed with the placeholder "Choose an account", open, focused, disabled, error with the message "Choose an account."

4. **Buttons.** Three buttons: "Send transfer" (primary), "Save draft" (secondary), "Close account" (destructive). Show each one in these states: default, hover, focused, pressed, disabled, loading (the label stays and a loading indicator is added). Hover, focused and pressed are shown as static samples.

5. **Transfers list.** A list titled "Recent transfers" with a search field (placeholder "Search transfers"), shown in four panels, one per state:
   - Loading.
   - Empty, with the message "No transfers match your search."
   - Error, with the message "Transfers could not be loaded." and a "Try again" button.
   - Populated, with these rows (date, recipient, amount, status):
     - 14 Oct 2026, Nora Jansen, $120.00, Completed
     - 12 Oct 2026, Elm Street Rentals, $1,450.00, Completed
     - 9 Oct 2026, City Power & Water, $86.40, Pending
     - 3 Oct 2026, Kaito Mori, $250.00, Failed
   The three statuses must be distinguishable from each other.

6. **Messages.** Four inline alerts, one per type:
   - Information: "Transfers made after 6 pm are processed the next business day."
   - Success: "Your transfer was scheduled."
   - Warning: "Your daily transfer limit is almost reached."
   - Error: "Your transfer could not be sent."
   Two toast notifications shown in place, each with a dismiss control: success "Transfer scheduled" and error "Transfer failed". A confirmation dialog shown open inside its own panel: title "Close account?", text "This action cannot be undone. Your remaining balance will be sent to your linked account.", buttons "Cancel" and "Close account".

7. **Transfer form.** One form shown twice, side by side on desktop and stacked on small screens. Fields: From account (select), To account number (text), Amount (text with the prefix "$"), Send on (date), Note (optional, multi-line text).
   - Left, error state: To account number shows "Enter a 10-digit account number." and Amount shows "Enter an amount greater than $0.00." An error summary above the form reads "Fix 2 errors to continue."
   - Right, success state: the form is replaced by a confirmation with the heading "Transfer scheduled", the text "$250.00 to Kaito Mori on 18 Oct 2026" and a "Make another transfer" button.

8. **Footer.** Copyright line "© 2026 Harbor Bank". Text links to Privacy, Terms and Accessibility (they may point to `#`).
