1// nx_font_variants.nx -- VARIATION SYSTEM: one glyph definition -> N visibly-distinct fonts via a STYLE VECTOR
2// {wr=stem weight, wh=horizontal weight (contrast), slant=oblique shear, xw=width %}. So if a variant reads too
3// close to some other font, change the vector and regenerate a distinct, drop-in replacement -- no re-drawing.
4// Weight/contrast bake into the stroke primitives; slant+width are a post-transform on the outline points.
5// Emits 5 variants of "NISHI" (Regular/Oblique/Condensed/Bold/Wide-Light) as separate self-validated .ttf +
6// a comparison page. license_tier: ORIGINAL expect_exit: 0
