// This file defines the data structures and helper functions for the template system.
//
// The template system uses Go's html/template package to provide:
// - Dynamic menu bars that can be customized per page
// - Template inheritance via layout.html
// - Type-safe data passing via structs
//
// To create a new page with a custom menu:
//  1. Create a PageData struct with your menu configuration
//  2. Call s.renderTemplate(w, status, "yourpage.html", data)
//  3. In yourpage.html, use {{template "layout" .}} and define content blocks
//
// See TEMPLATE_GUIDE.md for detailed examples and usage patterns.

// PageData holds the data passed to page templates.
type PageData struct {
	Title      string
	MenuGroups []MenuGroup
}

// MenuGroup represents a dropdown menu in the navbar.
type MenuGroup struct {
	Label string
	Items []MenuItem
}

// MenuItem represents a single menu item.
type MenuItem struct {
	Label     string
	URL       string
	IsDivider bool
}

// DefaultMenuBar returns the standard menu configuration.
func DefaultMenuBar() PageData {
	return PageData{
		MenuGroups: []MenuGroup{
			{
				Label: "Game",
				Items: []MenuItem{
					{Label: "Home", URL: "/"},
