/* ==========================================================================
   SUREFIRE STUDIOS — "STRIKE / BLUE" concept
   The quiet sibling. Same live-flame engine, opposite temperature.
   Blue flame is the hotter, more controlled burn — so the palette and the
   tone argue for each other instead of fighting.
   Loudness is removed structurally, not just recoloured:
     Anton caps  -> Manrope light, sentence case
     letter flare -> soft fade, no colour flash
     46vh flame  -> 34vh, lower gain
   ========================================================================== */
