/*
 * PianoSpot content pages (SEO articles).
 * Shared by every page cloned from /_templates/article.html.
 *
 * Reading surface is the app's cream; header, CTA card and footer reuse the
 * ink surfaces from the landing page (index.html) so the two feel like one site.
 * The landing page is dark-only and has no light/dark switch, so these pages
 * ship a single light scheme on purpose.
 *
 * Contrast (WCAG AA, checked with a script):
 *   ink #221D17 on cream #FBF5E7 ........ 15.4:1
 *   muted #5A5148 on cream ............... 7.1:1
 *   link #A84A1E on cream ................ 5.3:1
 *   link #A84A1E on cream-2 #F1E8D6 ...... 4.7:1
