% Custom macros and section formatting.

% \sectionheader — unified section header style, sans-serif, uppercase tracking,
% thin rule beneath. Used by both templates for consistency.
\titleformat{\section}
  {\headerfont\large\bfseries\MakeUppercase}
  {}{0pt}
  {}
  [\vspace{-0.4em}\rule{\linewidth}{0.4pt}]

\titlespacing*{\section}{0pt}{1.2em}{0.6em}

% \subsectionheader — for sub-entries (e.g., NeuroPose within Shu Lab).
\titleformat{\subsection}
  {\headerfont\normalsize\bfseries}
  {}{0pt}
  {}

\titlespacing*{\subsection}{0pt}{0.6em}{0.2em}

% \entryheader — a standard role/institution block. Two lines:
%   Line 1: \textbf{Organization} — \textit{Role}
%   Line 2: \small dates · location
\newcommand{\entryheader}[4]{%
  \noindent\textbf{#1}%
  \ifx&#2&\else~---~\textit{#2}\fi\\[0.1em]
  {\small\color{metagray}#3\ifx&#4&\else~\textperiodcentered~#4\fi}%
  \par\vspace{0.2em}%
}

% \pubentry — a publication/presentation line.
\newcommand{\pubentry}[3]{%
  \noindent #1. \textit{#2}. {\small\color{metagray}#3}%
  \par\vspace{0.35em}%
}

% \headerblock — document-top name and contact. Rendered differently by the
% two templates, so the actual layout is defined there; this is just a
% placeholder hook if we want to factor it out later.
