  File: meadnyte-site/assets/css/sigil.css
  Phase: 02_Index_Page_and_Menu

  Purpose:
  - Controls only the central Meadnyte sigil/logo image.
  - The uploaded video target requires a central portal mark.
  - The mark must be the actual asset: assets/img/logo.png.
  - Do not use a browser-rendered placeholder M.

  Future modification instructions:
  - Logo size has been accepted unless Aham explicitly reopens it.
  - Tune only sigil glow, image treatment, and central logo presentation here.
  - Do not place or style the upper-left woodmark here.
  - Do not style orbiting planets here.
