/* M-RECORDS v1 «Ночная смена»: dark cinematic studio.
   Theme: dark-only by brand decision (color-scheme: dark).
   Radius system: buttons are full-pill (--r-pill), photos and photo panels are 6px (--r-media), everything else is 0.
   Accent: one REC red-orange (#F0532E). Text on accent is near-black (5.4:1). Accent as text on --bg is 5.4:1.
   z-index scale: skip 100, header 50 (its menu lives inside it), callbar 40, content 0-3.
   Photo grade: the loud stage photos (electric blue, magenta, RGB console LEDs) get .grade so the REC accent stays the only saturated colour. */
