One-page LaTeX resume template

% ---------- Tagged PDF (optional) ----------
% Uncomment the next line for a tagged PDF: real reading order and list
% semantics for screen readers. Works with pdflatex on TeX Live 2023+.
% The LaTeX tagging project still labels this experimental, so it is off
% by default.

% -------------------- Semantic macros --------------------
% render.py (app/services/conversion/render.py) only ever emits calls to the 11
% macros below, with data already massaged (dates joined, "Present" resolved,
% link labels derived, etc.) but with ALL visual decisions — bold/italic, hfill
% alignment, icons, separators, list styling, gap sizes — owned here. See the
% macro contract in that module's docstring before changing signatures.
% Every template MUST define all 11, including \closebullets and \entrygap.
%
% No titlesec/xcolor here — sections are plain bold-uppercase text with no
% rules, keeping this the leanest package list of the five templates.

\newtoggle{citemnotfirst}
\newtoggle{bulletsopen}

% \closebullets closes the itemize list \rbullet opens. render.py calls it
% right after emitting the \rbullet run for an entry. \AtEndDocument is a
% defensive backstop only, in case a future call site forgets.

% Left-aligned, smaller than the other templates' headers — this template
% never spends vertical space it doesn't have to.

% No icons — plain label, middle-dot separated (\textperiodcentered is core
% LaTeX, no extra package needed). #1 (kind) is only checked for "email" so
% that case gets a real mailto: link; everything else just hyperlinks #2 when
% it's non-empty.

% Bold title, one step up from body size for contrast against the (now
% correctly normalsize) body text. No rule, minimal space above/below —
% density still comes from that tight spacing, not from a shrunk title.

  \togglefalse{skilllinenotfirst}%

% right-flushed with location appended after a comma when present.

% Minimal/empty — the density template proves \entrygap needed to be a macro:
% every other template puts real space here, Compact spends none.
