/* ESI Spa — site styles.
 * Ported from the June 2026 design (_dev/archive/esi-spa-new-2026-06/public_html/Assets/CSS/main/,
 * six files merged into one request), which reproduces the old Joomla template:
 * brand green #02922d (now #5ab24e, the logo green: PM 2026-10-23), logo green #5ab24e, 'Billion Web Font' headings.
 * Improved here: document lists (IR), data tables, image heroes, map loaded on click.
 * 2026-10-22: sharp and flat (square corners, lines instead of shadows, square buttons with a
 * chevron on the "go to" ones), after studioquagliero. The rounded version is archived in
 * _dev/archive/style-rounded-2026-10-22/ (project folder).
