boids4R 0.3.1

CRAN release: 2026-05-13

Updated DESCRIPTION for CRAN resubmission by removing the redundant trailing “for R” from the title and adding the formal Reynolds (1987) doi:10.1145/37402.37406 method reference.
Added the missing \value{} documentation for as_ggwebgl_spec() and described the ggwebgl_spec output structure.
Improved as_ggwebgl_spec() display defaults with high-contrast species and role palettes, emphasized current boids, faint recent trails, species-aware velocity vectors, and visible obstacle/predator rings.
Added alt text to the README logo image for pkgdown accessibility checks.

Added a 3D-focused flock, herd, swarm, and school vignette with 2D overhead variants where they clarify the same collective-motion pattern.
Added a swarm-art vignette showing how recorded frames can be turned into trail drawings, time-layered particle prints, negative-space obstacle compositions, and depth-coloured 3D projections.
Added compact, deterministic examples to exported function documentation so CRAN checks exercise the user-facing API.
Declared ggWebGL (>= 0.4.0) as the optional WebGL backend now that it is on CRAN, and guarded examples/tests against older adapter APIs.

Added a scenario-gallery vignette covering built-in 2D and 3D swarm scenarios, renderer-neutral frame summaries, species-level diagnostics, base graphics snapshots, and optional ggWebGL handoff.
Added a custom simulation workflow vignette showing explicit state, world, obstacle, predator, attractor, metric, parameter-sweep, and mixed-species 3D workflows.
Updated the obstacle-corridor scenario so initial boid positions are sampled outside obstacle discs.
Tuned custom workflow examples so the solid obstacle diagnostics show positive final obstacle clearance while preserving soft steering semantics.
Declared htmlwidgets as a suggested package for manual WebGL export examples.
