+# civilytics
+
+Brand themes, color palettes, and utility functions for
+[Civilytics Consulting](https://www.civilytics.com). The package provides a
+complete ggplot2 theme system drawn from the Civilytics design system ---
+warm paper backgrounds, civic-navy ink, and editorial typography --- along
+with 10 curated color palettes, logo composition helpers, and data-wrangling
+utilities for public-sector analysis.
+
+## Installation
+
+Install from the Civilytics Gitea server:
+
+```r
+# install.packages("remotes")
+remotes::install_gitea(
+  "Civilytics/civilyticsR",
+  gitea_url = "https://gitea.civilytics.org"
+)
+```
+
+## Quick start
+
+```{r quickstart, fig.height = 4, fig.width = 7, message = FALSE}
+library(civilytics)
+library(ggplot2)
+
+ggplot(mpg, aes(displ, hwy, colour = class)) +
+  geom_point(size = 2.5) +
+  scale_color_civilytics() +
+  labs(
+    title = "Fuel economy by engine displacement",
+    subtitle = "Highway MPG vs. engine size for 234 vehicles",
+    caption = "Source: EPA fuel economy data (ggplot2::mpg)",
+    x = "Engine displacement (litres)",
+    y = "Highway MPG"
+  ) +
+  theme_civilytics()
+```
+
+## Color palettes
+
+The package ships 53 named brand colors in `civilytics_colors` and 10
+curated palettes in `civilytics_palettes`. Use `civilytics_palette()` to
+retrieve colors by name, or pass palettes directly to the ggplot2 scales.
+
+### Palette gallery
+

+
+### Using palettes
+
+```{r palette-usage, fig.height = 3.5, fig.width = 7}
+# Discrete fill with the qualitative palette
+ggplot(mpg, aes(class, fill = class)) +
+  geom_bar(show.legend = FALSE) +

+  labs(title = "Vehicle counts by class", x = NULL, y = NULL) +

+
+# Continuous fill with a sequential palette
+ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
+  geom_tile() +
+  scale_fill_civilytics("seq_ember", discrete = FALSE) +
+  labs(title = "Old Faithful eruption density") +
+  theme_civilytics(grid = "none")
+```
+
+## Themes
+
+Three theme variants cover the most common output contexts. All share the
+same typographic structure and accept `grid` and `paper_bg` parameters.
+
+### Editorial (default)
+
+The default theme uses a warm paper background with horizontal gridlines ---
+an editorial, Pew-style layout.
+
+```{r theme-editorial, fig.height = 4, fig.width = 7}
+base_plot <- ggplot(mpg, aes(displ, hwy)) +
+  geom_point(aes(colour = factor(cyl)), size = 2) +
+  scale_color_civilytics() +
+  labs(
+    title    = "Engine size vs. highway fuel economy",
+    subtitle = "Colored by number of cylinders",
+    caption  = "Source: ggplot2::mpg",
+    colour   = "Cylinders",
+    x = "Displacement (L)", y = "Highway MPG"
+  )
+
+base_plot + theme_civilytics()
+```
+
+### Grid options
+
+The `grid` parameter controls which major gridlines are drawn.

+})
+gridExtra::grid.arrange(grobs = grid_plots, ncol = 2)
+```
+
+### Dark
+
+Dark navy background with light text, suitable for presentations or
+dashboards on dark surfaces.
+
+```{r theme-dark, fig.height = 4, fig.width = 7}
+base_plot + theme_civilytics_dark()

+    x = "Displacement (L)", y = "Highway MPG"
+  ) +
+  theme_civilytics(grid = "y")
+```
+
+## Logo utilities
+
+Add the Civilytics logo to any ggplot using the pipe-friendly
+`civilytics_logo()` or the lower-level `add_logo()` / `make_logo_grob()`.
+
+```r

-
-The goal of civilytics is to ...
-
-## Installation
-
-You can install the released version of civilytics from [CRAN](https://CRAN.R-project.org) with:
-
-``` r
-install.packages("civilytics")
-```
-
-## Example
-
-This is a basic example which shows you how to solve a common problem:
-
-``` r
-library(civilytics)
-## basic example code
-```
-
+
+# civilytics
+
+Brand themes, color palettes, and utility functions for [Civilytics
+Consulting](https://www.civilytics.com). The package provides a complete
+ggplot2 theme system drawn from the Civilytics design system — warm
+paper backgrounds, civic-navy ink, and editorial typography — along with
+10 curated color palettes, logo composition helpers, and data-wrangling
+utilities for public-sector analysis.
+
+## Installation
+
+Install from the Civilytics Gitea server:
+
+``` r
+# install.packages("remotes")
+remotes::install_gitea(
+  "Civilytics/civilyticsR",
+  gitea_url = "https://gitea.civilytics.org"
+)
+```
+
+## Quick start
+
+``` r
+library(civilytics)
+library(ggplot2)
+
+ggplot(mpg, aes(displ, hwy, colour = class)) +
+  geom_point(size = 2.5) +
+  scale_color_civilytics() +
+  labs(
+    title = "Fuel economy by engine displacement",
+    subtitle = "Highway MPG vs. engine size for 234 vehicles",
+    caption = "Source: EPA fuel economy data (ggplot2::mpg)",
+    x = "Engine displacement (litres)",
+    y = "Highway MPG"
+  ) +
+  theme_civilytics()
+```
+
+<img src="man/figures/README-quickstart-1.png" alt="" width="100%" />
+
+## Color palettes
+
+The package ships 53 named brand colors in `civilytics_colors` and 10
+curated palettes in `civilytics_palettes`. Use `civilytics_palette()` to
+retrieve colors by name, or pass palettes directly to the ggplot2
+scales.
+
+### Palette gallery
+
+<img src="man/figures/README-palette-gallery-1.png" alt="" width="100%" />
+
+### Using palettes
+
+``` r
+# Discrete fill with the qualitative palette
+ggplot(mpg, aes(class, fill = class)) +
+  geom_bar(show.legend = FALSE) +
+  scale_fill_civilytics() +
+  labs(title = "Vehicle counts by class", x = NULL, y = NULL) +
+  theme_civilytics(grid = "y")
+```
+
+<img src="man/figures/README-palette-usage-1.png" alt="" width="100%" />
+
+``` r
+
+# Continuous fill with a sequential palette
+ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
+  geom_tile() +
+  scale_fill_civilytics("seq_ember", discrete = FALSE) +
+  labs(title = "Old Faithful eruption density") +
+  theme_civilytics(grid = "none")
+```
+
+<img src="man/figures/README-palette-usage-2.png" alt="" width="100%" />
+
+## Themes
+
+Three theme variants cover the most common output contexts. All share
+the same typographic structure and accept `grid` and `paper_bg`
+parameters.
+
+### Editorial (default)
+
+The default theme uses a warm paper background with horizontal gridlines
+— an editorial, Pew-style layout.
+
+``` r
+base_plot <- ggplot(mpg, aes(displ, hwy)) +
+  geom_point(aes(colour = factor(cyl)), size = 2) +
+  scale_color_civilytics() +
+  labs(
+    title    = "Engine size vs. highway fuel economy",
+    subtitle = "Colored by number of cylinders",
+    caption  = "Source: ggplot2::mpg",
+    colour   = "Cylinders",
+    x = "Displacement (L)", y = "Highway MPG"
+  )
+
+base_plot + theme_civilytics()
+```
+
+<img src="man/figures/README-theme-editorial-1.png" alt="" width="100%" />
+
+### Grid options
+
+The `grid` parameter controls which major gridlines are drawn.
+
+<img src="man/figures/README-theme-grids-1.png" alt="" width="100%" />
+
+### Dark
+
+Dark navy background with light text, suitable for presentations or
+dashboards on dark surfaces.
+
+``` r
+base_plot + theme_civilytics_dark()
+```
+
+<img src="man/figures/README-theme-dark-1.png" alt="" width="100%" />
+
+### Slide
+
+Transparent background and larger base font (18 pt), sized for Reveal.js
+slides or PowerPoint exports.
+
+``` r
+base_plot + theme_civilytics_slide()
+```
+
+<img src="man/figures/README-theme-slide-1.png" alt="" width="100%" />
+
+### Facets
+
+Facet strips use the `paper_2` tint, with the title font.
+
+``` r
+ggplot(mpg, aes(displ, hwy)) +
+  geom_point(colour = civilytics_colors["navy_600"], size = 1.5) +
+  facet_wrap(~class, ncol = 4) +
+  labs(
+    title = "Highway MPG by vehicle class",
+    x = "Displacement (L)", y = "Highway MPG"
+  ) +
+  theme_civilytics(grid = "y")
+```
+
+<img src="man/figures/README-theme-facets-1.png" alt="" width="100%" />
+
+## Logo utilities
+
+Add the Civilytics logo to any ggplot using the pipe-friendly
+`civilytics_logo()` or the lower-level `add_logo()` /
+`make_logo_grob()`.
+
+``` r
