/* === DESKTOP / PRESENTATION MODE (>= 1400px) ===
   Above this width each slide is a fixed-height (1080px reference) "page"
   that JS scales by window.innerHeight/1080 — height always matches the
   window exactly, so there's never a scrollbar, like PowerPoint or Google
   Slides. Unlike a plain scale-to-fit, the stage's WIDTH is not fixed at
   1920px: JS sets it to innerWidth/scale, i.e. exactly the width that,
   after the same scale factor, fills the window horizontally too — zero
   leftover margin on either axis, no cropping, no stretching (the scale
   factor is uniform). The internal grids already use fr/%/flex widths,
   so they genuinely reflow into whatever width that turns out to be
   (narrower on a tall/narrow window, wider on an ultrawide one) instead
   of leaving blank space. Below 1400px (see the compact-mode block
   further down) the deck instead becomes a normal fluid, scrollable
   document — a full-height 1080px page has no room to scale down to on a
   phone without becoming unreadable. */
