"""core.quality.selection.load_search_mode — reads the download search
strategy from the quality profile.

'priority'      → today's behaviour: first satisfying source wins.
'best_quality'  → pool all sources, work best→worst by actual quality.

Default and any unknown value resolve to 'priority' so every existing
install keeps its current behaviour.
