How do you implement half-star support in a star rating?
Split each star into two halves with separate hover/click areas. Use clip-path or two overlaid elements. The left half sets 0.5, the right half sets 1.0. This allows precision rating like 3.5 out of 5.

Create 5 star elements. On mouseover, highlight up to the hovered star. On click, lock the rating. On mouseleave, reset the hover (keep the locked rating). Use Unicode stars (filled/empty). Add keyboard and ARIA support.
Half-star support, keyboard navigation (arrow keys, enter), reset button, readonly mode (display only), and ARIA attributes (role='slider', aria-valuenow, aria-valuemax). Also handle mouseleave to reset hover but keep locked rating.
Add tabindex='0' and role='slider'. Handle keydown: ArrowRight/Up to increase, ArrowLeft/Down to decrease, Enter to confirm. Update aria-valuenow. This makes the rating usable without a mouse.
