Update app.py

❌ Versi lama: panggil API di internet → ERROR (Space gratis ga bisa akses internet)
✅ Versi baru: model di-load langsung di Space → jalan 100% offline

❌ Versi lama: butuh setup HF_TOKEN
✅ Versi baru: GA PERLU TOKEN, ga perlu setup apapun

❌ Versi lama: model 3B (ga bisa di-load di Space gratis)
✅ Versi baru: model 0.5B (muat di RAM Space gratis)

Satu-satunya trade-off:
- Model lebih kecil → kualitas caption sedikit lebih rendah
- Tapi tetap bisa bikin caption yang usable!

 ✍️ CapGen AI — Caption Generator Indonesia
 ===========================================
-SETUP (HANYA 2 LANGKAH):
-------------------------
-1. Buat token gratis di: https://huggingface.co/settings/tokens
-   - Klik "New token"
-   - Type pilih "Read" (cukup ini saja)
-   - Copy token-nya
-
-2. Di Space kamu, buka: Settings → Repository Secrets
-   - Name:  HF_TOKEN
-   - Value: paste token tadi
-   - Klik Save
-
-SELESAI! Restart Space dan langsung bisa dipakai.
+GA PERLU TOKEN. GA PERLU SETUP APAPUN.
+Langsung jalan setelah Space selesai building.
