/*==========================================================
    Home "Resume" (design B = tabbed, same look as About D) — Views/Shared/_ResumePartial.cshtml
    Intro + buttons (sticky on desktop) | Work Experience / Education tabs
    -> Technical Skills / Core Competencies / Tools & Platforms tabs.
    Every class is prefixed rs- so the legacy .third-section / .resume-* / .mySkills
    rules in style.css and the Index inline <style> cannot leak in.
    Colours, type and radii come from tokens.css (every accent follows --brand).
