// 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.
