Create a minimalist dark‑mode wallpaper inspired by a high‑performance UI theme. Use a deep charcoal background (#0E0E0F) with subtle layered panels in #161718 and #1F2022. Incorporate very soft, low‑spread shadows for depth without harsh contrast. Add thin, elegant accent lines or geometric highlights in #3A8DFF to reflect the primary accent color. Use a clean, modern, tech‑aesthetic layout with balanced spacing and subtle gradients that stay within the dark palette. Avoid pure white; instead use soft light-gray elements (#E6E6E7 and #B8B9BB) only as minimal highlights. Overall mood: sleek, efficient, power‑optimized, and visually calm — perfect for an OLED/LED laptop display.
