Does the spec require these be 64-bit?

> +    FontPaletteIndex()

= default

I like to use 'const' for members that can only ever be set in the constructor.

> Source/WebCore/platform/graphics/FontPaletteValues.h:90
> +    unsigned integer { 0 };

You had int64_t in the changelog

> Source/WebCore/platform/graphics/cocoa/FontCacheCoreText.cpp:472
> +        int64_t rawIndex = basePalette.integer; // There is no kCFNumberUIntType.
> +        auto number = adoptCF(CFNumberCreate(kCFAllocatorDefault, kCFNumberSInt64Type, &rawIndex));
> +        CFDictionaryAddValue(attributes, kCTFontPaletteAttribute, number.get());

Can author-supplied values conflict with kCTFontPaletteLight, kCTFontPaletteDark?

Nope. In fact, our parser clamps to 32-bit. I'll update the changelog to be "unsigned" to match the implementation.

It depends if https://github.com/w3c/csswg-drafts/issues/6627 is accepted or not. If it's accepted (which I hope it is), there won't be a collision.

It looks like that, because this is used as a key in a hash map, and our hash map infrastructure uses operator= to overwrite the buckets in the table, all the fields have to be assignable. :(
