Curiosities

Visual polish

• Refined parchment artwork and colours on Overview, Collection, Discoveries, Compare and Settings.
• Added brushed-gold progress-bar textures to Overview and Compare, with a matching brushed finish for the blue comparison bar.
• Made card-reveal stars brighter yellow-gold.
• Added page-turn sounds for Previous, Next and mouse-wheel navigation in Collection, respecting the Sound setting.

Performance

• Optimized collection-progress calculations to avoid repeated catalogue scans and sorting.
• The collection set dropdown now builds when first opened and is reused afterwards, reducing initial album setup work.

Existing collection progress and unopened discoveries are preserved. No new cards or changes to discovery chances or dungeon boss guarantees.
