interface ThemeRendererInterface
Contract for theme rendering in the application.
Implementations are responsible for locating the active theme directory, resolving fallback themes when the primary is missing, and rendering header / content / footer templates in the correct sequence.
Each rendering method outputs HTML directly via include statements. Callers must not assume output buffering is active.
