/*
 * Template "Tech Summit" (Acara Kantor & Komunitas) — a seminar / workshop / tech-conference look. Dark-mode UI
 * in near-black navy, a vivid gradient accent (cyan → violet by default), static gradient-mesh glows, a faint
 * node-network pattern (img/network.svg, used as a mask so it takes the variant's gradient), and cool-grey
 * light sections in between. Signature pieces: the rounded app window with a gradient border
 * (sections/_window), the terminal card on the cover, the code-editor quote card, the organisation profile,
 * feature cards, calendar-event cards, the progress-bar countdown, speaker profile cards, the schedule app,
 * the sign-up card. Mobile-first, one column (~460px) on a deep backdrop on wide screens.
 *
 * Colours come from the chosen colour variant (template.json → <x-inv.head>):
 *   --inv-primary   action colour on light sections (buttons, links, labels; white text on it)
 *   --inv-accent    highlight colour on deep sections (labels, chips, icons)
 *   --inv-background / --inv-text   the cool-grey light sections and their text
 *   --inv-deep / --inv-surface / --inv-ondeep   the dark sections, their cards, and the text on them
 *                   (the "Terang Biru" variant turns these light: white sections with dark text)
 *   --inv-grad1 / --inv-grad2 / --inv-onbtn   the gradient accent and the text on it
 * Everything else is mixed from those, so a new variant only needs these ten colours.
 *
 * Section tones (set on each section in its partial): .ts-tone--light (cool grey + dot grid), --deep (dark,
 * gradient mesh + node network), --grad (the gradient band). Light and dark alternate.
 *
 * Motion only runs with html.inv-anim (set by <x-inv.head> unless the guest prefers reduced motion);
 * without it everything is shown finished. Nothing loops: every animation runs once.
 *
 * Contents: 1 base · 2 section tones & photo backgrounds · 3 shared pieces · 4 cover · 5 sections in page
 *           order · 6 forms (RSVP, wishes) · 7 shared components · 8 screen sizes · 9 motion
