   Ebru Subutay — Portfolio
   Theme: MINIMAL / ELEGANT — monochrome with a single burnt-orange accent.
   Inspired by kentokawazoe.com: persistent left nav rail, oversized thin
   uppercase display type, engineering-mono micro-labels, dark/light toggle.
   Pure vanilla CSS. No build. Dark is the default.
