Changes in version 0.0.0.9000                      

  - pz_stage_annotate() gains caption_side, the page default for the
    side of new pz_annotate_caption() captions. "bottom" remains the
    default and a per-call side still overrides it;
    pz_annotate_caption()'s side argument now defaults to NULL, meaning
    the staged value.

  - pz_serve_static() gains root, the directory to serve as the server
    root for an .html file. Use it when the page references assets
    outside its own directory, such as ../deps/styles.css; the handle
    URL points at the file relative to root. root is only supported for
    files, must be an existing directory containing the file, and can't
    be the filesystem root.

  - pz_open() serves .html files over HTTP with pz_serve_static() when
    httpuv is installed, so pages get HTTP-only behavior such as the
    browser's back/forward cache; pz_close() stops the one-off server.
    The file's directory is the server root, so pages referencing assets
    outside it need an explicit file:// URL. Without httpuv, .html files
    still open as file://.

  - pz_act_drag() gains named-only preview = TRUE: recorded HTML5 drags
    with a visible cursor carry a static source image and briefly settle
    to the same surviving source after drop. Unsafe or uncertain
    paparazzi redactions and optional preview failures warn and preserve
    the drag. preview = FALSE disables both the image and settling.

  - Persistent captions remain visible on the last GIF frame when
    recordings repeat captured frames, such as during pz_record_hold().

  - Breaking: pz_annotate_callout()'s arrow argument is renamed leader.
    TRUE (the default) draws a shaft with an arrow at the target, FALSE
    leaves a tooltip-style bubble, and a named character vector sets a
    decoration per end (c(start = "dot", end = "bar"); "none", "arrow",
    "dot", "bar").

  - Callouts are themeable and measurable: pz_annotate_callout() and
    pz_stage_annotate() gain fill and text_color for the bubble chrome
    (defaults keep the dark bubble with white text), stroke_width (one
    width shared with pz_annotate() marks, replacing the old 2-vs-3
    split, with decoration sizes scaled to it) and distance (the
    bubble-to-target gap, default 24 CSS px with a leader and 8 without,
    replacing the hardcoded 8px so leaders read as arrows).
    pz_annotate() badges follow their mark's color and gain per-call
    label_fill/label_text_color overrides.

  - Cursor overlays now use bundled SVG artwork for the full set of CSS
    cursor keywords, including wait, zoom-in, directional resize, and
    none. CSS cursor URLs use their fallback keyword; custom URL images
    are not drawn.

  - First development version. paparazzi drives a headless Chrome
    browser from R through chromote, with one |> chain per script: open
    pages and Shiny apps (pz_open(), pz_serve_shiny()), find elements
    (pz_loc(), pz_find()), act on them (pz_act_click(), pz_act_type(),
    pz_set_shiny_input(), ...), check the page with retrying
    expectations (pz_expect_*()), and capture screenshots and recordings
    (pz_screenshot(), pz_record()).

  - paparazzi requires R 4.1.0 or later, which added the native pipe |>.
    The pipe appears throughout the examples and documentation.
