Swap CAT Stack without a jump
Running text within 3% of the width, x-height within 5%
None of the fonts that look most like CAT Stack sets text to its width and x-height: a swap would move lines.
Fallback while it loads
Until CAT Stack loads, this sets Arial in its place at 131.5% of its size, so running text keeps CAT Stack’s width and lines keep their height: nothing moves when it arrives.
