+# panto-popular-themes
+
+`themes.popular` is a small, pure-Lua [pantograph](https://github.com/travisp/pantograph)
+extension. It registers the 19 popular palettes currently built into Panto as
+well as three Kanagawa variants, using the same role-to-SGR derivation as the
+core.
+
+## Install
+
+Add the rock to Panto's extension list:
+
+```toml
+[extensions]
+rocks = ["panto-popular-themes"]
+```
+
+The extension is named `themes.popular`; theme names are case-sensitive.
+
+## Themes
+
+- Tokyo Night
+- Catppuccin Mocha
+- Gruvbox Dark
+- Solarized Light
+- Solarized Dark

+
+## Provenance and mapping
+
+The first 19 palettes are faithful ports of the data and role derivation in
+`src/tui_theme.zig` (Tokyo Night 270–290, Catppuccin Mocha 291–311,
+Gruvbox Dark 312–332, Solarized Light 333–351, Solarized Dark 352–371,
+Nord 372–394, Dracula 395–416, Tokyo Storm 417–437, Tokyo Moon 438–458,
+Tokyo Day 459–479, Catppuccin Latte 480–500, Catppuccin Frappe 501–521,
+Catppuccin Macchiato 522–542, Gruvbox Dark Hard 543–563, Gruvbox Dark
+Soft 564–584, Gruvbox Light 585–605, Gruvbox Light Hard 606–626,
+Gruvbox Light Soft 627–647, Dracula Soft 648–666; derivation
+`makePalette` 1046–1105). Their source pins are the ones documented by Panto:

+- Tokyo Night: [`folke/tokyonight.nvim` at `cdc07ac`](https://github.com/folke/tokyonight.nvim/tree/cdc07ac78467a233fd62c493de29a17e0cf2b2b6)
+- Catppuccin: [`catppuccin/nvim` at `edefef7`](https://github.com/catppuccin/nvim/tree/edefef779ab08ce1a4a404713e3012b0d202bd35)

+- Solarized: [`maxmx03/solarized.nvim` 3.6.0 at `c0dfe1c`](https://github.com/maxmx03/solarized.nvim/tree/c0dfe1cbfabd93b546baf5f1408f5df7e02e2050)
+- Nord: [`nordtheme/vim` at `f13f5df`](https://github.com/nordtheme/vim/blob/f13f5dfbb784deddbc1d8195f34dfd9ec73e2295/colors/nord.vim)
+- Dracula: [`Mofiqul/dracula.nvim` at `ae752c1`](https://github.com/Mofiqul/dracula.nvim/tree/ae752c13e95fb7c5f58da4b5123cb804ea7568ee)
+
+Kanagawa is taken from the primary [`rebelot/kanagawa.nvim`](https://github.com/rebelot/kanagawa.nvim)
+repository at pinned commit
+[`bb85e4bfc8d89b0e62c8fa53ccdd13d12e2f77b3`](https://github.com/rebelot/kanagawa.nvim/tree/bb85e4bfc8d89b0e62c8fa53ccdd13d12e2f77b3),
+using its [`colors.lua`](https://raw.githubusercontent.com/rebelot/kanagawa.nvim/bb85e4bfc8d89b0e62c8fa53ccdd13d12e2f77b3/lua/kanagawa/colors.lua)
+and [`themes.lua`](https://raw.githubusercontent.com/rebelot/kanagawa.nvim/bb85e4bfc8d89b0e62c8fa53ccdd13d12e2f77b3/lua/kanagawa/themes.lua).
+Wave, Dragon, and Lotus map Normal foreground/background, Comment, semantic
+syntax groups, NormalFloat, Title/Directory, and diagnostics into Panto's
+17-color palette. Kanagawa authors real `DiffAdd`/`DiffDelete` backgrounds,
+so those are retained; the 20% canvas/status tint is used only when a source
+palette does not provide a diff background.
+
+As in core, each palette emits all 40 role SGR strings and `reset = ESC[0m`.
+Activation first performs a read-only lookup for each name and registers only
+names that are not already present. This makes activating the extension
+alongside Panto's built-ins or a third-party palette safe: any existing
+identical or different registration wins, while malformed values for a new
+registration still raise.
+
+The stock `panto` palette and Panto's five original palettes—Tidepool Tumble,
+Mossmallow, Peachy Pudding, Plum Pips, and Gilded Inkblot—stay in core and are
+not registered here.
+
+## Development
+
+```sh
+panto lua _selfcheck.lua
+PANTOGRAPH_DIR="${PANTOGRAPH_DIR:-../pantograph}"
+REPO_DIR="$(pwd)"
+(cd "$PANTOGRAPH_DIR" && panto lua "$REPO_DIR/scripts/verify-against-core.lua")
+```
+
+The second check uses the real Panto theme registry: it compares every role
+in the extension's computed snapshots with the 19 corresponding core snapshots,
+reporting the theme and role for any byte mismatch, then activates the
+extension to validate registration of the three Kanagawa additions.
