Buttons are outline-led — 1–2px #333333 at a fractional 3.5–5.25px radius with UPPERCASE labels at +1px tracking — switching to a 2px #cd4c20 border when active or on sale. The newsletter input does something distinctive: it fills with rust #b85021 on focus rather than drawing a ring. The mini-cart close button sets outline:none with no replacement, so a ring is shown here as the recommended fix.
The radius scale is fractional, built on a 3.5px base (3.5 / 5.25 / 7 / 10.5) — rounding to whole numbers breaks it. Only two real shadows exist, both directional and strong for lifted overlays; 23 elements carry a fully transparent placeholder shadow. Motion is 0.2s cubic-bezier(.4,0,.2,1) with just three keyframes (fadeInAnimation, rotate--2, rotate--3) and a deliberately slow 16.8s hero carousel. Scrims run on a 208deg diagonal, not a flat vertical.
