/* The actual scrolling container for the canvas. It fills the card-body

   The "center when fits, scroll-naturally when overflows" pattern is tricky
   in both flex and grid because default centering CLIPS overflow on the
   start side. Two layered fixes:
     1. `place-items: safe center` — modern keyword, supported in all current
        browsers; falls back to start-alignment when content overflows.
     2. `margin: auto` on the child — older-browser fallback that works the
        same way in any formatting context (block, flex, grid).
   Either alone would suffice; together they ensure correct behavior even on
   slightly older Safari versions. */
/* The actual scrolling container for the canvas. It fills the card-body
   so the canvas can pan/scroll when zoomed.

   Centering an item that may overflow its scroll container is famously
   tricky — `justify-content: center` / `place-items: center` (in both flex
   and grid) CLIP the overflow start, making the top/left of zoomed content
   unreachable.

   The reliable cross-browser pattern that works in every direction:
     * Container: `display: flex` with start-alignment defaults (no centering).
     * Child: `margin: auto`.

   `margin: auto` distributes leftover space evenly when the child fits, and
   collapses to zero when it overflows — at which point flex's natural
   start-alignment kicks in and the user can scroll freely. */
