/*<--------------------------------------------------->
<!-- FAQ (section component)                        -->
<!----------------------------------------------------->
* Description:
    Frequently-asked-questions section for #faq.
    Grouped by category with a borderless accordion
    using native <details>/<summary>. Smooth bidirectional
    animation via CSS grid-template-rows trick +
    @starting-style for entry. JS handles closing so the
    transition completes before [open] is removed.
* Dependencies:
    - style.css (custom properties, sectionHeader, .content)
    - faq.js (smooth closing animation)
