Smu Stats Beamer

%==============================================================================
%  slide.tex  --  Unofficial SMU (Southern Methodist University) Beamer theme
%
%  Self-contained: stock beamer + tikz.  The brand assets SMUbg.png /
%  SMU-Dedman.jpg / SMUlogoWhite.png are picked up automatically if present,
%  and the deck degrades gracefully without them.
%
%  Build:  pdflatex slide   (run twice so the tikz overlays settle)

%==============================================================================
%  HOW TO STRUCTURE YOUR SLIDES  -- read this before adding content
%
%  Required hierarchy:   \section  ->  \subsection  ->  \begin{frame}{...}
%
%  1. Every content frame must live inside a \subsection, which lives inside a
%     \section.  Declare \section / \subsection on their OWN line, BEFORE the
%     \begin{frame} they introduce -- never put them inside a frame.
%
%  2. Do NOT place a frame directly under a \section with no \subsection.
%     The header progress bar measures the current subsection's position within
%     its section, so a frame with no subsection shows an EMPTY bar.
%
%  3. A subsection MAY contain several frames.  The header bar simply holds that
%     subsection's number across all of them -- that is expected, not a bug.
%
%  4. The \subsection name drives the table of contents, the PDF bookmarks, and
%     the header progress-bar steps.  The frame title in \begin{frame}{...} is
%     only the on-slide header.  They may match or differ -- you do NOT have to
%     repeat the subsection name as the frame title.
%
%  5. Keep the title page and table-of-contents frames (the [plain] ones above)
%     ABOVE the first \section so they stay out of the TOC and bookmarks.
%
%  6. The TOC and both progress bars are computed from slide.aux across runs.
%     After you add, remove, or reorder any (sub)section, compile twice
%     (or run `latexmk -pdf slide.tex`) so they settle to the right values.
