 * SCVGN Training — branding skeleton on top of Bootstrap 5.3.
 *
 * This is deliberately a skeleton, not a redesign: it names the SCVGN palette
 * once and styles the handful of classes the templates already use. base.html
 * sets data-bs-theme="dark", so these variables layer on Bootstrap's own dark
 * theme rather than fighting it.
 *
 * Nothing here may move into a template. The CSP is default-src 'self' with no
 * 'unsafe-inline', so an inline style= attribute or a <style> block is dropped
 * by the browser — quietly, in production, where nobody is watching.
