/**
 * AutoFit AI Search - Chat Assistant Stylesheet
 *
 * v3.7.7 - COMPACT EMPTY-STATE IN CHAT (UI POLISH):
 *
 *          Mirrors the shortcode-side change from the same
 *          release so the empty-state hint in the chat window
 *          is visually consistent with the shortcode card.
 *
 *          Changed in .autofit-section-empty (chat scope):
 *            • padding:       24px 16px → 12px 14px
 *            • font-size:     15px → 12.5px
 *            • icon size:     36px → 20px
 *            • icon margin:   14px → 4px
 *            • max-width:     none → 300px (centered)
 *            • border-radius: 10px → 8px
 *            • line-height:   1.8 → 1.5
 *
 *          Mobile breakpoints adjusted proportionally:
 *            @media (max-width: 480px):
 *              padding 22px 14px → 12px 14px
 *              font    15px → 12.5px
 *              icon    32px → 20px
 *              margin  12px → 4px
 *
 *          Because the chat window is narrower (380px on
 *          desktop) than the shortcode card, the max-width is
 *          300px (vs 340px on the shortcode) so the box still
 *          reads as a centered hint rather than a full-width
 *          block.
 *
 *          NO other rule in this file changed.
 *
 *          FILES CHANGED IN v3.7.7 (4 total):
 *            * assets/css/autofit-shortcode.css
 *            * assets/css/autofit-assistant.css            (this file)
 *            * includes/core/class-autofit-assets.php
 *            * autofit-ai-search.php
 *
 *          NOTHING ELSE CHANGED -- every other rule is
 *          byte-for-byte identical to v2.15.6.
 *
 * v2.15.6 - CHAT GRID LAYOUT FIX (UX BUG):
 *
 *          PROBLEM:
 *            The chat's product sections (main / near_matches /
 *            suggestions) reuse AutoFit.Section.render(), which
 *            adds the class .autofit-sc-products-grid. That class
 *            is a CSS Grid whose fallback column count is 2 on
 *            mobile (media max-width: 900px) and 4 on desktop —
 *            controlled by --autofit-columns-mobile / -columns.
 *
 *            Those CSS variables are only defined on
 *            .autofit-search-card[data-autofit-instance]
 *            (shortcode). The chat window never received them,
 *            so the chat grid always fell back to 2 (mobile) /
 *            4 (desktop) columns — regardless of the store
 *            owner's setting.
 *
 *          FIX:
 *            Added a scoped override at the end of this file
 *            that forces the chat grid into a vertical stack
 *            (display:flex; flex-direction:column).
 *
 *          NO OTHER CHANGES — every other rule is byte-for-byte
 *          identical to v2.15.3.
 *
 * v2.15.3 - CHAT INPUT-GROUP LIGHT IN DARK MODE (UX FIX).
 * v2.15.2 - THEME RING AROUND TOGGLE IN CHAT (VISUAL POLISH).
 * v2.15.1 - NEUMORPHIC THEME TOGGLE IN CHAT (REDESIGN).
 * v2.15.0 - DARK/LIGHT MODE + THEME TOGGLE IN CHAT.
 * v2.14.4 - BOLDER / LARGER EMPTY-STATE MESSAGES IN CHAT.
 * v2.14.3 - FIX: TOGGLE SPACING.
 * v2.14.1 - TOGGLE POLISH IN CHAT.
 * v2.14.0 - COLLAPSIBLE SECTIONS + BOLDER TITLES.
 * v2.13.3 - THREE-SECTION STYLES IN CHAT (Phase 7).
 * v2.13.0 - TYPO CORRECTION BANNER (Phase 4).
 * v2.12.0 - CHAT SORT CONTROL STYLES.
 * v2.11.0 - CHAT RESULTS PAGINATION STYLES.
 * v2.9.7  - CHAT RECENT-SEARCH CHIPS VISIBILITY FIX.
 * v2.8.52 - CHAT CARD READABILITY.
 * v2.8.46 - HYBRID PRODUCT BADGES.
 * v2.8.20 - Price layout (white-space: pre-line).
 * v2.8.17 - Mobile UX.
 * v2.8.5  - Suggested Products styles for the chat surface.
 * v2.8.1  - FIX: Corrected malformed CSS comment.
 * v2.5.9  - Added: .autofit-custom-icon-img / .autofit-custom-icon-text.
 * v2.5.8  - Square aspect ratio for chat product images.
 * v2.5.6  - Fixed syntax errors.

✅ v2.15.3 CHANGES (UX FIX):
   The chat input-group now stays LIGHT in dark mode,

     • input-group border:       #334155 → #cbd5e1
     • focus-within background:  #0f172a → #ffffff
     • focus-within border:      #3b82f6 → #2563eb
     • input color:              #f1f5f9 → #1e293b
     • input placeholder:        #64748b → #94a3b8
     • clear-btn background:     #1e293b → #ffffff
     • clear-btn border:         #334155 → #cbd5e1

/* =========================================================
✅ v2.15.6: CHAT GRID → VERTICAL STACK (UX FIX)
=========================================================

PROBLEM:
  Product cards inside the chat sections (main /
  near_matches / suggestions) are rendered with the class
  .autofit-sc-products-grid — a CSS Grid whose fallback
  column count is 2 on mobile (media max-width: 900px) and
  4 on desktop.

  That column count is controlled by CSS custom properties:
    --autofit-columns         (desktop, fallback 4)
    --autofit-columns-mobile  (mobile,  fallback 2)

  Those variables are only defined on
  .autofit-search-card[data-autofit-instance] (shortcode),
  via wp_add_inline_style() in class-autofit-assets.php.
  The chat window (#autofit-chat-window) never received
  them — so the chat's grid always fell back to 2 columns
  on mobile and 4 columns on desktop, regardless of the
  store owner's "تعداد ستون‌های موبایل" / "تعداد ستون‌های
  دسکتاپ" settings.

FIX:
  Force the chat's product grid into a vertical stack
  (display:flex; flex-direction:column). This is the
  correct layout for a 380px-wide chat panel, and it
  matches the store owner's expectation of a clean
  single-column list.

SCOPE:
  Scoped exclusively to #autofit-chat-window. The
  shortcode surface (.autofit-search-card) is untouched
  and continues to honor --autofit-columns / -mobile
  exactly as before.

  A duplicate rule is injected inline from
  class-autofit-assets.php (maybe_inject_toggle_inline_css)
  for hosts where this external file returns 404
  (e.g. mr-shock.com). Both rules are identical.
