   Jevaughn Octable — portfolio styles
   Theme: black + emerald + silver. Obsidian and charcoal backgrounds so photos
   and color stand out like lights on a plant floor; emerald for buttons, links
   and selected items; mint for glowing numbers; champagne gold only for small
   markers (heading slashes, bullets, labels). Faint engineering line art as watermarks.
   To change the look site-wide, edit the variables in :root.
