/*
 * Stylesheet for Soham Shirolkar's personal site.
 *
 * This design draws inspiration from glassmorphism: cards use
 * semi‑transparent backgrounds and a subtle blur filter to create a
 * frosted glass effect. Typography uses Montserrat throughout for a
 * clean, modern feel. Colors are soft and neutral, allowing content to
 * take centre stage.
