/* ============================================================
   Glow Theme
   Layers a glowing look on top of the base template using the
   BLC logo's own two-tone palette (see :root in style.css):
     --primary : #022A6A  (navy — the logo's outer ring / BLC text)
     --accent  : #FC0005  (red  — the logo's inner ring)
     --light   : #F3F6F9
     --dark    : #191C24
   Navy carries structure (fills, text); red carries the glow on
   the elements meant to catch the eye. Loaded once, site-wide,
   right after style.css.
