Use case: text-localization. Edit the supplied existing HN advertisement. Replace ONLY lowercase brand wordmark "hardnerd" with EXACT case-sensitive "HardNerd": uppercase H, lowercase ard, uppercase N, lowercase erd. Spell H a r d N e r d. Keep the same gradient colors, clean bold font, approximate wordmark size, icon-to-wordmark gap, baseline, centered composition and generous brand-to-tagline spacing. Keep the H/lime-glasses icon EXACTLY unchanged. Keep white Chinese tagline EXACTLY "硬核架构，品质专线，全球网络畅通无阻", same small size and placement. Preserve background charcoal, teal/purple glow, wide dimensions, tiny 广告 and all other details. No additional changes.
