• Rating slider: Set ratings by slider adjustment.
• Simplified rating display: Only shows 👍 likes, 👎 dislikes, and ⭐ average.
• Stable icon layout: Icon space preserved even if iconURLHdr is missing — no broken images or layout shifts.
• Enhanced sorting: Name-based ascending/descending added; newest/oldest SCID sorting retained.
