iOS Safari chrome now matches the landing canvas
On iOS Safari, the status bar and header above the homepage now match the page's canvas color — light gray in light mode, near-black in dark mode — instead of showing a white or black seam at first paint or after switching themes. The fix uses static light/dark theme-color metas rather than a JavaScript sync, so it applies as soon as the page loads.
This is specific to iOS Safari's theme-color support; it doesn't change how the homepage looks on desktop or Android Chrome.
