/** Tier boundaries — ordered from highest to lowest
 *
 * Indicators (work surfaces — CLI · code · docs · receipts):
 *   ✪ Proof Seal (Trophy 100% — work glyph; social still uses 🏆; brand uses Trophy Mark PNG)
 *   ★ filled star (gold — orange)
 *   ◆ filled diamond (silver — cyan)
 *   ◇ open diamond (bronze — deep cyan, one rung below silver)
 *   ● filled circle (mid tiers)
 *   ○ open circle (low — dim)
 *   ♡ heart (empty — good luck)
 *
 * All three 100% glyphs mean the same score: ✪ work · 🏆 social · Trophy Mark (PNG) visual.
