   LUMIÈRE GEMOLOGICAL — STYLESHEET
   Design language: obsidian ground, champagne-gold facet accents, deep
   emerald as a secondary note. Display type is a high-contrast serif used
   sparingly for headlines; a geometric sans carries body copy; a monospace
   face is reserved for data — prices, stats, contact details, report-style
   figures — echoing a gemological grading report.
