Team Analyzer for Showdown от surfnWOB

Team Analyzer adds a defensive type-matchup matrix to the classic teambuilder on play.pokemonshowdown.com, and renders the same matrix alongside any shared team paste on pokepast.es. As you build a team — or as you read someone else's paste — the extension calculates each Pokémon's resistances, weaknesses, and immunities to all 18 attacking types and surfaces team-wide defensive holes you might otherwise miss.

Features:
• Per-Pokémon defensive matrix that updates live as you add or remove team members
• Modifiers for defensive abilities (Levitate, Flash Fire, Water Absorb, and 12 more) and items (Air Balloon, Ring Target, Iron Ball)
• Totals row showing how many team members are weak, resist, or are immune to each attacking type
• Color-coded cells (red = weak, green = resist, dark = immune) with a multiplier/symbol toggle
• Yellow column highlight on attacking types your whole team is weak to with no resists or immunities — your real defensive gaps
• "≥3 weak" flag on attacking types that hit half your team for super-effective damage
• Pokepaste support: open any pokepast.es paste and the same matrix renders next to the team, with format auto-detected from the paste's "Format:" header when present
• Themed for both Showdown's light and dark UI; the pokepaste panel also follows pokepaste's own light/dark toggle

How it works:
The extension only runs on two sites: play.pokemonshowdown.com (the classic teambuilder) and pokepast.es (rendering the analyzer panel beside shared pastes). On Showdown it reads the team you're editing and renders the panel inside the teambuilder; on pokepaste it reads the paste body that the site already serves to your browser and renders the panel in the right gutter. The team contents, your username, the URLs you visit, and the paste body itself are never transmitted off your machine. The extension does send a small set of anonymous, opt-out usage events (panel mounted, placement mode, format detected, handled errors, pokepaste fetch/parse failures) to help us understand how the extension is used; click the "A" toggle in the panel header to disable analytics.

Permissions:
Host access to play.pokemonshowdown.com and pokepast.es is required — those are the two sites the extension augments, and it requests no other permissions.
