Replace domain-specific (education/PDP) recipe stories with generic
content. Fix TopBar action buttons using properly styled light-on-dark
buttons instead of invisible IconButton tertiary. Use the real NSW
waratah SVG logo. Add shared _story-helpers for TopBar actions and logo.
Add DetailPage template for single-record/profile/document views with
constrained width and tab support.
