The audience opens decks on their own device (often a phone via the share QR), so the bottom toolbar is a real touch surface. Its icon buttons sat at ~40x40 (24px SVG + 0.5em padding) which falls under WCAG 2.5.5's 44x44 floor. Add a 44px min-width/min-height to .tool and a matching min-height on the .info counter slot so the bar reads as a single 44px strip and the 24px icons stay centered with breathing room.
