  Animated call-to-action link. Light sweep on hover, arrow slides right.
  Colors come from the parent section's --lib-accent / --lib-accent-text / --lib-text vars.
  Inspired by Uiverse.io button patterns; rewritten for themes, no dependencies.

  @param {string} label - Button text
  @param {string} [url] - Link target; renders a disabled-looking span when blank
  @param {string} [style] - 'primary' (default), 'outline' or 'text'
  @param {boolean} [new_tab] - Open the link in a new tab
  @param {boolean} [arrow] - Show the trailing arrow (default true)

  @example
  {% render 'lib-button', label: section.settings.button_label, url: section.settings.button_url, style: 'outline' %}
{% enddoc %}

{%- liquid
  assign btn_style = style | default: 'primary'
  assign show_arrow = true
  if arrow == false
    assign show_arrow = false
  endif
-%}
