Class: SportsItem
Sports and fitness equipment. COICOP 09.4 (sport and recreational equipment). Note: bicycles are placed here by domain convention; COICOP assigns them to Division 07 (Transport). The domain decision reflects how social organisations actually sort and store these items.
Dual-track assessment (defined in SportsCategory, categories/sports.yaml):
protective_gear subcategory → SportsProtectiveAssessmentEnum
Wear grade is insufficient for safety-critical items — structural
damage may not be visually apparent after impact (e.g. a cracked
helmet inner shell invisible under an intact outer shell).
all other subcategories → condition_grade (wear grade)

the range is overridden via slot_usage to CategoryEnum.
