 # CV Templates and Tailoring Guide
@@ -100,6 +100,10 @@ Two related patterns are fine and should be kept:
 - `\vspace{1pt}` immediately after `\section{...}` (between section heading and first item) - this is between the heading and the list, not between list items.
 - `\vspace{3pt}` between top-level `\cventry` blocks in Professional Experience or Education - this gives breathing room between roles and renders consistently.
 
+### Section headings must match the CV's language (important)
+
+Section headings such as `\section{Core Competencies}`, `Professional Experience`, `Education`, `Languages`, `Publications`, `Honors and Awards`, `References` (and any others your template defines), plus the `Available upon request.` line under References, are all **literal English text baked into the template** - they do not translate themselves. Whenever the CV language (see `CV language` in the candidate profile) is not English, translate every one of these too, whatever they are, not just the body prose - a CV with a fully localized profile statement and bullets sitting under untouched English section headers reads as sloppy and inconsistent, and it's an easy thing to forget precisely because the prose translation is the obvious, visible part of the job. Worked example for Spanish: `Competencias Clave`, `Experiencia Profesional`, `Educaci\'on`, `Idiomas`, `Publicaciones`, `Distinciones y Premios`, `Referencias`, `Disponibles a solicitud.` The same rule applies for any other target language - check this explicitly during the verification pass.

 ### Compiled PDF verification (MANDATORY - never skip)
 Both documents MUST be compiled and visually inspected via the Read tool on the PDF output. "Looks fine in the .tex" is not acceptable - LaTeX page-break decisions are unpredictable. Iterate until these all pass:
