Font Smoothing

SHOULD

SHOULD: Apply `-webkit-font-smoothing: antialiased` so subpixel rendering does not make text look heavier than the designed weight.

Apply -webkit-font-smoothing: antialiased for better text legibility

body { -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; }

Bad

Good

Why it matters

Subpixel antialiasing can make text appear heavier than designed, especially on macOS. Applying antialiased rendering produces text that more closely matches the intended font weight and appears crisper on high-DPI displays.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
