GUIDE / 01
Padding and extrude do different jobs.
One separates areas. The other extends pixels. Telling them apart prevents misreading the exported frame rectangle.
01 — Padding
It reserves transparent distance around content plus extrude. FRAME offers 2, 4, or 8 px. It does not change frame w/h.
CONTENT
02 — Extrude
It copies the sprite’s outer row, column, and corners by 0, 1, or 2 px. It sits outside the JSON frame and may reduce filtering halos; it does not simulate mipmaps or guarantee an engine.
