   AIKOHI COFFEE — STYLESHEET
   
   Ini adalah file CSS utama untuk website Aikohi.
   CSS (Cascading Style Sheets) digunakan untuk mengatur
   tampilan visual dari elemen-elemen HTML.
   
   Struktur file ini:
   1. CSS Variables (Design Tokens)
   2. Reset & Base Styles
   3. Utility Classes
   4. Components (Navbar, Hero, About, Menu, dll)
   5. Animations
   6. Responsive Design (Media Queries)

/* ===================================
   1. CSS VARIABLES (Design Tokens)
   
   CSS Variables (Custom Properties) memungkinkan kita 
   menyimpan nilai yang bisa dipakai ulang di seluruh file.
   Diawali dengan -- dan diakses dengan var(--nama).
   
   Contoh: var(--color-primary) → akan menghasilkan #2C5F2D
   =================================== */
