     A `.ai` opened from its editing data opens its Objects on Path groups live, with their path, their objects in order along it, Pivot and Rotate, and their art where the file draws it; a group whose spacing has been dragged, or with options an Objects on Path group doesn't hold, opens as a plain group (`crates/eps/src/import/ai/tests.rs`).
     `.ai` symbol definitions and placed instances open as live symbols, in the Symbols panel's order; an instance of a symbol that isn't read, or whose appearance differs from its symbol's, comes in as the page draws it (`crates/eps/src/import/ai/tests.rs`).
     In a `.ai` opened from its editing data, an object in a pattern's art or a brush's art with an art style VectorCraft reads opens as itself with its effects live, as an object on a layer does, and an object in a pattern's art keeps the id of a graphic style in the file's list (`crates/eps/src/import/ai/tests.rs`).

     Blends and envelopes in the definitions of a `.ai`'s symbols, patterns and brushes' art count against the same per-file limits on blend layout and envelope checks as the layers' art, so a file with many definitions does not get those limits again for each one (`crates/eps/src/import/ai/read/directives.rs`).
     A `.ai` or EPS whose editing data has brushes opens with the file's Calligraphic, Scatter, Art and Bristle brushes in the Brushes panel in place of the default ones, in the file's order: the Calligraphic size, roundness and angle with their variation, the Scatter size, spacing, scatter and rotation, the Bristle settings, and the Scatter and Art brushes' art (Art brushes in the older and newer forms of their objects). A brush library `.ai` (brushes and no layers) opens from its PDF part with its brushes, so Other Library lists them. An Art brush in Tints keeps that colorization. Pattern brushes and brushes that can't be read are left out with a note. Paths with a Calligraphic brush, and paths with an Art brush in the newer form at 100% in Tints that stretches art of solid-filled paths unflipped, open as the path with the brush on its stroke. Paths with an Art brush in the older form, and other brushed paths, still come in as their drawn look (part of #372 and #637; `crates/eps/src/import/ai/tests.rs`, `crates/eps/src/import/tests_native.rs`).
     In a `.ai` opened from its editing data, a path or type object with Offset Path, Outline Object or Outline Stroke on the whole object opens as itself with those effects live, in their order and shown or hidden; on a fill or stroke of type they stay on that fill or stroke. Offset Path keeps its Offset, Joins and Miter Limit, and Outline Stroke takes its width from the stroke. An Offset Path with a setting missing, out of range or not read keeps the drawn art, as does a path with a Path effect on one fill or stroke (`crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`, `crates/eps/src/import/tests_native.rs`).
