   EnergyExperts — generic CSV upload dialog (assets/js/ee-csv-upload-dialog.js)

   Uses the tokens of the account dashboard (ee-create-account.css :root):
   --surface, --background, --border-light, --border-medium, --text-primary,
   --text-secondary, --radius, --radius-large, --shadow-lg, --transition.
   No colour, radius or shadow is invented here, and the buttons and inputs are
   the existing .btn / .form-input / .form-label / .form-hint classes.
