Pixel-perfect design systems behind a $5 trillion market cap

Last week, while reviewing a cross-platform component in Figma, I found the spacing between button text and icons was off by 1px. A new team member said, "You can't see it with the naked eye." It took me half an hour to explain why Apple's Human Interface Guidelines don't even allow a 1pt margin of error. This isn't obsession; it's the foundation Apple has spent ten years laying for user experience. Today, as Apple's market cap breaks $5 trillion, I'm not staring at the curve, but at that 44pt minimum tap target size established since the first iPhone.
