   Luis Fernando Varas — Portfolio
   Layout concept: centered, professional portfolio in a Spider-Man
   palette (red / royal blue / white / navy) with a light robotic
   accent: blueprint grid, corner brackets, a blueprint arm watermark,
   and purposeful motion. Short copy, high contrast, colour blocks.
