GhostSplit.gg for Twitch.tv Autor: GhostSplit.gg

GhostSplit Chat Theme restyles Twitch's chat to match the look of GhostSplit's split-view chat client: tighter rows, softer per-user colors, and compact text-pill badges (SUB, MOD, VIP, FOUNDER, TURBO, PRIME, BITS) instead of Twitch's noisy image badges. Works equally well on native Twitch chat and on chat rendered by 7TV, so 7TV, BetterTTV, and FrankerFaceZ can stay installed alongside without breaking.

What you get:
• Text-pill badges. Image badges next to usernames are replaced by compact role chips. Custom channel sub badges and event badges are hidden so the row stays clean. English and Spanish Twitch UI locales are both mapped.
• Softened username colors. Neon-bright Twitch usernames are mixed toward a readable base, with a luminance check that re-darkens names that would otherwise wash out, reds, yellows, and lime greens stay legible on dark backgrounds.
• Tighter row chrome. Reduced padding, baseline-aligned badges and usernames, a hard cap on inline emote heights (no more giant 7TV emotes blowing up rows), and a faint card tint on each row.
• Distinct system rows. Channel-points redeems get a red card with a 4-pixel left rail; watch-streak milestones get a gold card; sub, resub, and raid notices get a blue notice card. Inline reply quotes get a purple left rail so threads read as separate.
• Dark and light theme support. Both Twitch themes are styled, with palette-appropriate pill colors and high-contrast text on each. The theme switch follows Twitch's own UI flag, no extra setting required.
• Cheer-effect rows preserved. When Twitch paints a halo + animated body around a cheer message, the theme defers to that effect cleanly rather than fighting it with its own card chrome.
• Loaded indicator. A small ghost icon in Twitch's top navigation confirms the theme is active. Non-interactive, purely a visual reminder.

Privacy:
No network requests. No localStorage, sessionStorage, or cookie access. No storage, tabs, webRequest, or scripting permissions. No analytics, no telemetry, no remote code. The extension only needs host_permissions for .twitch.tv/. Everything else is pure DOM manipulation and CSS.

Preserved on purpose: the bits / cheer button, channel-points balance and claim flow, all redeem / milestone / cheer-tier badges, Twitch's collapse-chat and theatre-mode controls, 7TV's settings button and emote menu.
