ggconsulting (development version)

Foundation (prompt 01)

• ct_theme() builder composed via theme_sub_*() helpers and routed through element_geom() so from_theme()-aware geoms inherit the palette’s main colour (ink) and a default linewidth.
• theme_strategy() archetype as a preset path.
• Five starter palettes: strategy_navy, strategy_emerald, strategy_crimson, strategy_azure, strategy_slate.
• ct_col() / ct_line() / ct_point() mechanical wrappers for explicit-override use at the call site.
• ct_set_defaults() / ct_unset_defaults() for true aesthetic defaults (currently geom_point size = 2.5), autoloaded on library attach with an opt-out option.
• has_font() internal helper.

CI (prompt 02)

• R-CMD-check workflow across macOS, Windows, Ubuntu (R release) and Ubuntu (R devel).
• test-coverage workflow via covr + Codecov v4.
• README badges: R-CMD-check status, Codecov coverage, License: MIT.

Scales and palette preview (prompt 03)

• scale_color_ct() / scale_fill_ct() — discrete scales backed by ggconsulting palettes; interpolate and emit a cli::cli_warn() when n exceeds the palette size.
• scale_color_ct_c() / scale_fill_ct_c() — continuous variants via ggplot2::scale_color_gradientn() / scale_fill_gradientn().
• British-spelling aliases: scale_colour_ct(), scale_colour_ct_c().
• ct_palette_show() — swatch preview for a single palette, a custom hex vector, or every shipped palette faceted.

Finance and editorial archetypes (prompt 04)

• theme_finance() — serif preset (Source Serif 4 → Georgia → Times New Roman → serif) with regular-weight title, a lighter major gridline, and denser defaults (density = "tight", context = "report") tuned for printed pages over slides. Defaults to the finance_classic palette.
• theme_editorial() — serif preset with an italic subtitle and slightly larger, tighter-leaded title. Defaults to the editorial_warm palette.
• ct_theme() gained a font_fallback argument; .resolve_font() now recognises "sans", "serif", and "mono" as guaranteed terminal fallbacks.
• Six new palettes: finance_classic, finance_steel, finance_burgundy, editorial_warm, editorial_clay, editorial_oxide. The catalog is now 11 palettes (5 strategy + 3 finance + 3 editorial).

Locale and formatters (prompt 05)

• ct_locale("pt-BR" | "en-US") — session-scoped locale switch stored in options(ggconsulting.locale). Does not touch Sys.setlocale(); portable across Windows / Linux / macOS CI.
• fmt_number() — locale-aware number formatter (1.234,5 / 1,234.5).
• fmt_brl() — Brazilian Real formatter; always renders as R$ with a non-breaking space, regardless of active locale. Supports style = "accounting" for parens-wrapped negatives.
• fmt_currency() — uses the active locale’s currency symbol.
• fmt_pct() — fraction-to-percent (0.5 → "50%").
• fmt_delta() — always-signed percentage-point-style deltas (+1,2pp / -0,3pp / 0,0pp).
• fmt_month() — Date / POSIXct → localised month string; ships its own pt-BR and en-US month tables (no LC_TIME reliance).

Data-aware polish (prompt 06)

• ct_finish() — companion to ct_theme() that runs after the geom layer is built (via an ggplot_add() S3 method) and can:
  • inject value labels above bars / next to points (values = TRUE or "auto")
  • reorder a categorical x by y (sort = "asc" | "desc")
  • format labels via shortcut names (label_fmt = "brl" | "number" | "pct" | "delta") or a user-supplied function
  • highlight specific x values with the theme’s main colour and mute the rest with muted_color (default #A8A4A0, a warm-leaning neutral that reads under both cool and warm palettes)
  • label the last point of each line series (end_labels = TRUE)
  • geom-aware scale expansion (expand = "auto") — y room above columns, right-side room for line endpoints
