/* ---- OPTIONAL: Mix-Blend-Variante ----
   Wenn .spo-grid die Klasse `blend` zusätzlich bekommt, fallen die Boxen
   weg und Logos werden via mix-blend-mode auf den Paper-BG gemischt.
   Vorteil: cleaner, "premium"-Look. Risiko: dunkle Logos werden auf
   Paper unsichtbar, farbige Logo-Hintergründe schlagen durch.
   Zum Testen: `class="spo-grid tier-team blend"` setzen. */
