Speed Is a Design Decision
Performance isn't a developer's chore. It's a designer's discipline.
There's a tendency to treat speed as an engineering problem that happens after the design is finished — a last-mile clean-up, the same way you'd tighten margins before printing. That framing is why so many beautiful sites feel sluggish.
Every design decision has a weight. A second hero font, a full-bleed video, a parallax layer, a third-party widget that drags in a megabyte of script — each one is fine in isolation. Stacked, they turn a fast site into a slow one, and the only person who notices the trade-off is the visitor who closes the tab.
The discipline is simple: design like every kilobyte costs you something, because it does. Pick one display font and commit. Earn each piece of motion. Cut what you can't justify out loud. The fastest sites tend to also be the calmest ones to look at — that isn't a coincidence.
