Who are you,
in type? surveillance by typography.

Every program you install drops fonts onto your system. Microsoft Office leaves Calibri. Adobe Creative Cloud leaves Myriad Pro and a long tail of pro faces. JetBrains IDEs leave JetBrains Mono. Mathematica leaves its own glyphs. From CSS alone, a page can probe which of these resolved on your machine, and assemble an oddly specific profile of who you are.

method

probe: Declares an @font-face with src: local("FontName"). Renders "FontName" against a fallback baseline on a canvas.
mechanism: The browser's font engine resolves the local face, or fails. JavaScript measures the pixel width of the rendered text.
comparison: The CSS rule is the comparison. The width difference is the comparison.
