Make slide deck paginated by default with viewport-scaled slides

[Copilot]

Slide deck opened as a vertically-scrolled page by default, requiring F5/F to enter presentation mode. Slides also rendered at fixed 1280×720 without scaling to the viewport.

Changes

• Paginated by default: Auto-enter presentation mode on page load so slides display one-at-a-time like PowerPoint
• Viewport scaling: Dynamically scale slides to fill available screen real estate via Math.min(innerWidth/1280, innerHeight/720) with a resize listener
• Nav help updated: Reflects new default — Esc overview · Dbl-click to resume replaces F to start · Esc to exit

Overview mode is still accessible via Escape; double-click or F returns to paginated view.

function scaleSlides() {
  if (!document.body.classList.contains('presentation-mode')) return;
  var scale = Math.min(window.innerWidth / 1280, window.innerHeight / 720);
  slides.forEach(function (s) {
    s.style.transform = 'translate(-50%, -50%) scale(' + scale + ')';
  });
}

// Start in presentation mode by default
enterPresentation();
