 * Stylesheet for the Static Mode version of the Saptarshi Sadhu portfolio.
 * This is the non-3D, clean counterpart to 3d.css.
 * Design will be filled in — this is the scaffold.
 *
 * Structure mirrors 3d.css but overrides animations, 3D effects, and heavy
 * glassmorphism with a crisp, clean, high-performance static aesthetic.
