Build a three-column feature section with Tailwind CSS: each column pairs a line icon in a tinted rounded square with a short heading and two lines of supporting copy. Keep headings to three words, copy under 120 characters, and give icons a consistent 40px box with the accent color at 10% opacity as background. Add a section heading above the grid and let columns stack on mobile.
