/* Forge — Creative Agency / Portfolio HTML5 Template
   Structured-corporate design language: one brand color, no gradients, no decorative icon
   glyphs, sharp edges. Work-thumb imagery is deliberately abstract (solid color blocks) since
   this is a template, not a real studio's actual case-study photography. Vanilla CSS. */
