/* Wide-screen side rails (rails.js). Hidden below 1300px, where nothing changes.
   Geometry, all overridable on :root or #app:
     --rails-col   width kept clear for the centre column (match the widest .screen)  720px
     --rails-gap   space between the column and each rail                            24px
     --rails-edge  minimum space to the depth gauge and to the screen edge            20px
     --rails-max   widest a rail gets                                                 360px
   The column is centred in .stage, which starts after the gauge, so its centre sits at
   50% + gauge/2. Each rail hugs the column and narrows to fit on smaller screens
   (216px at 1300px, 300px from 1468px, 360px from 1588px with a 720px column).
   Heights: rails are only as tall as their content and scroll inside if the screen is short. */
