/* ==========================================================================
   Homepage slot placement.
   ROOT-CAUSE FIX (2026-09-12, r8): .stchat-panel and .st-rank-panel used to
   be two SEPARATE grid items sharing the sidebar column across two DIFFERENT
   grid rows — but .stchat-panel's row (row 3) was SHARED with the much
   taller .st-updates-main (Yeni Bölümler) in the main column, and a CSS
   Grid row's height is always the tallest item in that row. So row 3 grew
   to match Yeni Bölümler's full height, and Popüler Seriler (row 4) only
   started after that huge row ended — a giant blank gap between the two
   sidebar panels that had nothing to do with either panel's own content.
   Fix: homepage.php now wraps both in one <div class="st-sidebar"> — a
   single independent flex column, sized by ITS OWN content (chat + a small
   gap + Popüler Seriler), placed as ONE grid item. Whatever height Yeni
   Bölümler needs no longer has any bearing on where Popüler Seriler sits;
   it always sits directly below the chat panel by exactly `gap`.

   DESKTOP (>=900px): main column = Yeni Bölümler only; sidebar column =
   Canlı Sohbet directly above Popüler Seriler, sticking together as a unit
   while the (usually much taller) main column scrolls past:
     [ main: Yeni Bölümler ]   [ sidebar: Canlı Sohbet -> Popüler Seriler ]

   MOBILE (<=899px): .st-sidebar is display:contents — the wrapper itself
   generates no box and takes no part in the flex layout, so .stchat-panel
   and .st-rank-panel rejoin .st-home's flex flow exactly as if the wrapper
   were never there, each keeping its OWN existing `order` (they are NOT
   adjacent on mobile: Bugünün Gözdeleri -> Canlı Sohbet -> Yeni Bölümler ->
   Kütüphanem -> Popüler Seriler -> Yeni Seriler, unchanged from prior
   revisions).
