// VoteWidget — the "which draft would you ship?" reader poll.
//
// Static markup only. The fetch to vote-service, the localStorage voter id,
// and the click handler are task 16's job. The button toggle state lives
// here so the layout matches the legacy page at first render.
//
// CSS hooks asserted by scripts/verify.mjs that must survive in the new
// architecture:
//   .vote-widget        — the outer wrapper
//   .vote-buttons       — the button row
//   [aria-pressed=true] — the selected state
//
// The aria-label / role="group" on the inner cluster carries the state to
// assistive tech — colour alone is not enough. This is asserted in the
// task brief and lives in the same hook surface.
