   CHANGE LOG • LOG DE CAMBIOS:
	25/08/2026 - Changes to remove top border and excess whitespace padding from first main section site-wide
	29/08/2026 - Reduced utility nav margins to tighten top layout
	30/08/2026 - Header Flex Alignment & Compact EN | ES Language Switcher 
	01/09/26: ver 2: Monolingual Rationalization: Completed the clean separation of bilingual templates
  into dedicated single-language English and Spanish pages across the site (about.html / quien-soy.html,
  contact.html / contacto.html, minimalism.html / minimalismo.html). 
  Navigation & Anchor Alignment: Standardised primary <nav> menu links across all HTML templates 
  to route directly to specific section anchors (#about-en, #quien-soy, #contact-form-container, #main-gallery).
  Viewport Scroll Offset: Added global smooth scrolling and section header padding (scroll-margin-top) in styles.css 
  to prevent content headings from clipping against the top browser edge on mobile and tablet screens.  
  Bottom Navigation Jumps: Integrated dual return links ("Top of Content ↑" / "Main Menu ↑") 
  above the legal footer across content pages for seamless navigation on long viewports.
   02/09/2026 - Conmutador de idioma superior EN | ES para dispositivos móviles.
   04/09/2026 - Estilos para enlaces de títulos y reducción de espacio vertical 
   05/09/26 - Update styles.css: enforce solid menu background opacity and boost dropdown contrast.
     Added explicit solid background-color (#ffffff) to nav container and dropdown sub-menu items across desktop and mobile viewports. 
	 Elevated box-shadow depth to preserve contrast against dark background imagery.
