Design a simple, iconic, and modern logo for an AI mentor platform named "SENSEI". Create an abstract geometric symbol using interwoven or looping shapes, inspired by logos like ChatGPT, Gemini, and Claude. The mark should feel like continuous flow, intelligence, and connection. Subtly hint at the letter "S" within the form. Style: ultra minimal, bold, symmetric or near-symmetric, strong negative space, clean vector geometry. Color: single color or two-tone maximum (electric blue #00A3FF on dark background #0A0F1E, or pure black and white). Typography: optional — clean sans-serif font, modern and spaced, include "SENSEI" if needed. Flat design, no gradients, no shadows, no 3D, no complex details. The logo must be highly recognizable, scalable, and suitable as an app icon (like ChatGPT or Gemini).
