Square, vertical and rule-of-thirds versions of a deck.

/mira-squared

Generates a square (1:1, 1080×1080) version of a deck from the 16:9 original, or creates square slides from scratch. Writes a new index-1x1.html next to the original (centered by default, optionally left/right aligned). For Instagram feed, LinkedIn, etc.

/mira-vertical

Generates a vertical (9:16) version. Each content slide keeps only the main title at the top and a tall, standardized animation canvas below; the title auto-shrinks to fit at most two lines, and each animation's axis is reworked for portrait (horizontal flow becomes vertical, side-by-side comparison becomes stacked). Writes index-9x16.html. For Reels, Shorts, TikTok, Stories.

/mira-thirds

Reframes a deck on the rule of thirds without changing the aspect ratio. Pushes each slide's content into columns 1 and 2 of a 3×3 grid (the left two-thirds) and leaves the right column free — for you to overlay text, a lower-third or the presenter's video in editing. Works on top of 16:9, 1:1 or 9:16. Writes a -thirds file. Free side is the right by default; can be flipped.
