/* ATLAS_PRE_FILTER_DASH -- event-display skin (mk4).
   Palette taken from an ATLAS event display: black space, detector blue for
   structure, track orange for action and emphasis, calorimeter yellow, muon-chamber
   green, muon-track red. Verdict colours reuse the display's own meanings:
   PASS chamber green, FIX cell yellow, DROP muon red. Physics plots stay on WHITE
   plates. One loud element per page: the title block, or the detector on sign-in. */

/* ---- HOUSE RULE: the page is exactly the viewport ------------------------
   Every sheet in this app is one screen. The document never scrolls; a region
   that needs to scroll says so, and scrolls inside its own box.

   Three things make that work, and all three are needed:

     1. the shell is a FIXED height, not a min-height. A min-height lets content
        push the page taller, which is the scrollbar you are trying to remove.
     2. every flex/grid child in the chain carries min-height: 0. Without it a
        child refuses to shrink below its content and forces the parent to
        grow -- the most common cause of an unexpected scrollbar by a distance.
     3. 100dvh, not 100vh. On mobile 100vh is the viewport WITHOUT the browser
        chrome currently on screen, so a 100vh page is taller than what you can
        see. 100vh stays first as the fallback for older engines.

   For a new page: give its root `height: 100%; min-height: 0`, put the
   scrolling region behind `overflow: auto`, and put `min-height: 0` on every
   box between the two. Do not put a min-height in viewport units anywhere.
   The narrow breakpoint at the bottom of this file deliberately hands scrolling
   back to the document -- a phone cannot honour this and should not try. */
