/* ============================================================
   PDF Sıkıştırma — PREMIUM dark-purple SaaS design (Visuo/Mufi)
   "WAO on open": gradient orbs, glassmorphism, 3D tilt,
   micro-interactions. Zero frameworks, zero remote assets.
   Fonts: Plus Jakarta Sans (OFL), self-hosted latin + latin-ext
   (Turkish: ğ ş İ ı ç ö ü) in assets/fonts/.
   Class names and IDs are identical to the current build: app.js
   depends on them, so nothing was renamed.
   Design tokens from the reference homepage-premium system.
   NOTE: .tool-card entrance animation uses fill-mode `backwards`
   (not `both`) so the JS 3D-tilt (inline transform) keeps working —
   animation fill `forwards` would permanently override inline styles.
