Summary

• index.html: added datetime="" to the clock time element (updated each tick by clock.js)
• css/components.css: replaced color-mix(in srgb, ...) with rgba(0, 212, 255, 0.3) for broader browser compatibility
• css/responsive.css: grid-auto-rows now uses clamp(200px, calc(...), 400px) to prevent tiles from being too small or too large on tablet viewports
