/* ===============================================
   FULL-PAGE SECTIONS — one screen = one scroll
   ===============================================
   Loaded LAST (its own <link> after process.css) so it wins over every
   component file without needing !important everywhere.

   >>> EVERYTHING IN THIS FILE LIVES INSIDE ONE MEDIA QUERY. <<<

   That is not cosmetic. Because this sheet loads after style.css, any rule
   written at the top level here would beat _responsive.css's media queries —
   later sheet wins at equal specificity, media query or not. A bare
   `.section-title { font-size: clamp(...) }` in this file would therefore
   silently kill every phone and tablet override in _responsive.css. Keeping
   the whole thing gated means full-page mode is purely additive: outside the
   gate the site behaves exactly as _responsive.css describes.

   The gate is min-width 1201px + min-height 600px:
     - 1201px, because process.css stacks .timeline into a column at ≤1200px
       and five stacked steps cannot fit one viewport. Snapping there would
       make the bottom of the section unreachable.
     - 600px tall, because below that no amount of clamping fits the content.

   Two halves inside the gate:
     1. Snapping   — native CSS scroll-snap on the document scroller.
     2. Fitting    — every section locked to exactly one viewport, contents
                     sized in vh so they shrink with the window.

   Why native snap and not a wheel handler: `scroll-snap-type` is resolved by
   the compositor. It cannot deadlock the page, it works with the keyboard,
   trackpad, touch and the scrollbar, and it needs no scroll-position
   bookkeeping — which is exactly what broke the previous JS version.

   HARD RULE: because snapping is `mandatory`, a section taller than the
   viewport becomes unreachable at the bottom. If you add content to a
   section, shrink something else here — do not let a section grow.
