Templates with Pages with different Sizes

Sometimes a user might need a template with pages with multiple sizes and we need to support that.

For example, a news portal template might have:

• Page 1: Instagram Reels size (1080×1920) — vertical video cover or story card

• Page 2: Instagram Feed size (1080×1080) — square post for the main feed

• Page 3: Facebook Cover size (1200×630) — banner for article sharing

• Page 4: Twitter/X Post size (1600×900) — landscape card for link previews

• Page 5: YouTube Thumbnail size (1280×720) — video thumbnail for embedded content

This way, a single template can generate all the creative assets a news portal needs for distributing one article across multiple channels, ensuring brand consistency while respecting each platform's optimal dimensions.
