Proposal: Proportional variable font or custom axis

I've found that proportional typefaces (with variable widths rather than monospacing) are generally easier to read, even with code. However, proportional typefaces lack code specific features, like ligatures and differentiation.

I'm excited by Monaspace's texture healing feature, as it improves readability and reduces visual rivers in monospaced fonts. This could make it a great candidate for a variable font or custom axis that's spaced proportionally.

We should be able to start with default glyphs, and optionally use texture conflict data to adjust widths of glyphs dynamically, rather than replacing them with monospaced glyphs.

No files, tests, or entry points are named. Start by reviewing Monaspace’s texture healing feature and how default glyphs and texture conflict data are represented. Done would require a defined and validated approach for proportional widths through a variable font or custom axis.
