  @moduledoc """
  Tooltip component with PhiaTooltip vanilla JS hook.

  Ejected from PhiaUI — you own this copy. Customise freely.

  ## Example

      <.tooltip id="user-tip" delay_ms={200}>
        <.tooltip_trigger tooltip_id="user-tip">
          <button>Hover me</button>
        </.tooltip_trigger>
        <.tooltip_content tooltip_id="user-tip" position={:top}>
          This is helpful context.
        </.tooltip_content>
      </.tooltip>

  ## Hook setup

  Register PhiaTooltip in your app.js:

      import PhiaTooltip from "./hooks/tooltip"
      let liveSocket = new LiveSocket("/live", Socket, {
        hooks: { PhiaTooltip }
      })
