quartose 0.2.0

• Fixed a bug where format.quarto_tabset() did not escape </> in captured output from arbitrary R objects (e.g. a tibble’s <fct> column-type tag), which could be parsed as an unknown HTML tag by quarto/pandoc (#1). ?quarto_format now documents the resulting escaping policy: only quarto_tabset()’s captured object output is escaped this way; quarto_span()/quarto_div() content is validated rather than captured, and quarto_markdown() passes raw markup through untouched by design.
• Fixed a bug where the internal quarto_plot wrapper used to capture ggplot2 objects inside quarto_tabset() had its class silently stripped by c()-based list flattening in format.quarto_tabset(). Plot capture now preserves the quarto_plot class and is dispatched via a dedicated knit_print.quarto_plot() method instead of relying on ggplot’s own knit_print method by coincidence.
• quarto_div() now validates its content argument: every element must be a character vector or a quarto_object, mirroring the checks already applied by quarto_group()/quarto_markdown(). Previously an unsupported object (e.g. a bare list, a model object, or a number) would pass silently into quarto_div() and only fail later inside format(). An empty div (content = NULL, content = list(), or content = character(0)) is still permitted.
• quarto_tabset() now raises a specific error (“content has no names, and names was not supplied…”) when content is unnamed and names isn’t supplied, instead of the generic (and misleading) “names must be a character vector”.
• quarto_tabset() now auto-detects and renders a wider range of graphics objects as images, rather than only ggplot2 (#2): base R recorded plots (grDevices::recordPlot()), grid grobs, lattice/trellis objects, and patchwork objects (which subclass ggplot2 and already worked once the quarto_plot flattening bug was fixed). Added as_quarto_graphic(), an escape hatch that tags an arbitrary object so it is treated as a graphic even when quartose doesn’t otherwise recognize its class. This adds grDevices and grid to Imports; both are base R packages bundled with every R installation, so this does not add any new installation burden.
• quarto_div() now supports graphics objects in content (#3), using the same detection and rendering machinery as quarto_tabset(). format() returns a single string as before when content has no graphics objects, and a list (mixing strings and plot objects, as quarto_tabset() already does) when it does.

quartose 0.1.0

• Initial CRAN submission. This release establishes the core design that later versions build on: constructors validate and store their arguments unprocessed (R/class.R), format.<class>() methods turn a stored object into Quarto syntax on demand (R/format.R), and a shared print.quarto_object()/knit_print.quarto_object() pair (R/print.R) gives a human-readable console summary via print() and emits the actual Quarto markup via cat() when knitr::knit_print() is called inside a results: asis chunk.
• Provides six constructors, all returning an object with parent S3 class quarto_object plus a class-specific subclass: quarto_section() for headers; quarto_tabset() for tabsets, with optional section title and manual tab naming via names; quarto_div() and quarto_span() for divs and spans with CSS classes; quarto_markdown() for passing raw markdown/character content through untouched; and quarto_group() for bundling several quarto objects so they print together.
• quarto_tabset() content can include ggplot2 objects: these are captured and rendered only when knit_print() is called, via an internal quarto_plot wrapper. quarto_div() does not yet support plot content.
• Basic argument validation (R/validate.R) checks types and lengths for each constructor (e.g. level must be a whole number between 1 and 6; quarto_group()/quarto_markdown() require their content elements to all be quarto objects or character vectors, respectively), raising informative errors via rlang::abort().
• Imports: cli, knitr, purrr, rlang, utils. Suggests: ggplot2, quarto, rmarkdown, spelling, testthat (>= 3.0.0).
