All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

## Notes {#notes}
|
|
|
|
- `downloadUrl` menunjuk ke bagan histogram PNG yang telah dirender, menampilkan distribusi R, G, B, dan luminansi.
|
|
- `bins` berisi array 256-nilai mentah untuk setiap channel (red, green, blue, luminance), cocok untuk merender visualisasi kustom.
|
|
- `stats` menyediakan mean, median, dan deviasi standar per channel.
|
|
- `mean` dan `max` adalah field ringkas yang kompatibel-mundur.
|
|
- Gunakan skala `log` ketika histogram didominasi beberapa puncak dan Anda ingin melihat detail pada bin yang lebih rendah.
|
|
- Input HEIC, RAW, PSD, dan SVG di-decode otomatis sebelum analisis.
