/* ==========================================================================
   Kyklos — Purchase & Sales Cycle
   app.css — design token, animasi, dan lapisan komponen bersama

   PEMBAGIAN TANGGUNG JAWAB (disengaja, jangan dicampur):
   - Tailwind  -> layout, spacing, grid, breakpoint responsif  (di HTML)
   - app.css   -> design token, animasi, transisi, komponen berulang

   TEMA: dark adalah bawaan; light didefinisikan sebagai penimpaan token.
   Tidak ada satu pun warna yang ditulis di luar blok token di bawah ini —
   termasuk warna chart, yang dibaca JavaScript dari properti kustom ini.
