<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Editor: Improve how `min`/`max` font sizes are calculated for fluid typography.

- Where no fluid max values are set (e.g., single or custom font size values), the "size" value will act as the maximum value in a `clamp()` function.
- In the absence of any fluid `min`/`max` values, the lower bound rule of `>16px` will be enforced. This applies to custom values from the editor or single-value `theme.json` styles. Font sizes below this will not be clamped.
- In a preset, if a `fluid.min` value has been specified, the lower bound rule of `>16px` won't be enforced on this value. Presets with a fluid object therefore, give precedence to theme author's values.
- In a preset, if there is NOT a `fluid.max` but there is `fluid.min`, use the incoming "size" value as the `max`.
- In a preset, if there is NOT a `fluid.min` but there is a `fluid.max`, use `size * min_size_factor` as the `min`. The lower bound rule of `>16px` is enforced here, because the block editor is computing the `min` value. This is consistent with the way minimum sizes are calculated for single or custom values.
