<button class="btn-130" aria-label="Increase"><svg width="18" height="18" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="3" stroke-linecap="round"><path d="M12 5v14M5 12h14"/></svg></button>Prompt
A round 56px dial button with an off-centre radial highlight (white at 35% 30% to #dfe3e8), 1px #b8bec7 border, a 6px pale bezel ring plus a 1px darker ring outside it (both via box-shadow), a 3px drop shadow and an inline plus icon in #334155. Hover darkens the icon; active scales to 0.96 and swaps the drop shadow for an inset 3px shadow so it looks pressed in. Focus 2px blue outline offset 8px so it clears the bezel.
