/* KARCOMFORT — "Lights On".
   Detailing is the craft of making light behave on a surface, so the studio is lit, not dark.
   Brand colours (from Kanak): YELLOW, RED, WHITE, BLACK — already exactly 4.
   white paper + black ink + yellow (brand fill) + red (action).
   Yellow-on-black is workshop vernacular (hazard tape, tools), not generic automotive blue.
   Yellow NEVER carries text on white — it fails contrast. It is a fill, with black on top.
   WhatsApp green is functional, never decoration. */
