  ║  PLACEHOLDER RULE — READ BEFORE EDITING                      ║

  ║  The .placeholder class adds a yellow highlight and dotted   ║
  ║  underline to every value that has not yet been confirmed    ║
  ║  by the company owner.                                       ║
  ║                                                              ║
  ║  DO NOT delete the .placeholder rule.                        ║
  ║  If you delete it, unconfirmed values become invisible and   ║
  ║  will be published as fact. Instead, replace the             ║
  ║  [CONFIRM: ...] text with real values, then remove the       ║
  ║  class="placeholder" attribute from that specific element.   ║
  ║                                                              ║
  ║  Work through CONFIRM-THESE.md to clear every placeholder    ║
  ║  before going live.                                          ║
