% Frame Title Template
% ==============================================================================

% Custom frame (slide) title template
\defbeamertemplate*{frametitle}{uni}
{
    \vspace{15pt}%
    % Depth is explicitly set to 0pt to prevent vertical layout shifts 
    % caused by characters with descenders (e.g., 'g', 'p', 'y')
    \begin{beamercolorbox}[dp=0pt, leftskip=\titlelf]{title}
        \usebeamerfont{frametitle}%
        \insertframetitle%
    \end{beamercolorbox}%
}

% ==============================================================================
% Frame Title Continuation
% ==============================================================================

% Format continuation indicators for multi-frame slides (e.g., using allowframebreaks)
% Renders lowercase roman numerals enclosed in parentheses: (i), (ii), (iii)...
\defbeamertemplate*{frametitle continuation}{uni}{%
    (\insertcontinuationcountroman)%
}
