     A `.ai` or EPS symbol library, whose editing data holds symbol definitions and their list but no layers, opens with those symbols in list order, each with its registration point. Other Library… in the Symbols panel's Symbol Libraries Menu imports the symbols of the file you pick ([Create or import symbol libraries](https://helpx.adobe.com/illustrator/desktop/manage-objects/traces-mockups-symbols/create-or-import-symbol-libraries.html)) and lists such a library's symbols in a library panel. A `.ai` or EPS read as its PDF part or page because its layers can't be used also gets the symbols defined before its layers (`crates/eps/src/import/tests_native.rs`, `crates/eps/src/import/ai/tests.rs`, `cmd::fileio::tests_aiimport::a_symbol_library_in_a_ai_file_without_layers_loads_its_symbols`).
     In a large canvas `.ai` or EPS ([Large canvas FAQ](https://helpx.adobe.com/illustrator/desktop/add-and-import-files/start-a-new-file/large-canvas-faq.html)), or a `.ai` whose page is in larger units, opened from its editing data, VectorCraft reads the symbol definitions in the same units as the layers. When the file opens at its full size, each symbol's art, strokes and effects are scaled with the layers, and each instance keeps its own scale and rotation and draws where and as large as before. A new instance comes in at the symbol's full size, the size of an instance at 100% in the file. A symbol library from such a file comes in at the same size, and opacity masks on the layers that don't move with their object are scaled with the layers too. Editing data that VectorCraft wrote keeps its symbols and those masks at their own size, as its `.ai` save writes them (`tests_native::a_large_canvas_eps_keeps_its_symbols_at_the_pages_size`, `a_large_canvas_ai_keeps_its_symbols_at_the_pages_size`, `a_large_canvas_ai_vectorcraft_wrote_keeps_its_symbols_at_their_own_size`, `a_symbol_library_in_larger_units_comes_in_at_the_pages_size`, `build::candidate_tests::scaling_the_symbols_keeps_their_instances_in_place`, `scaling_a_read_document_scales_unlinked_opacity_masks`).
     A `.ai` or EPS opened from its editing data whose text document makes the type of every text object that shows takes all its type from the text document: each text object stays in its own group, frame and layer, the page's type isn't matched with them, a file of more than 5,000 text objects still opens with its layers, and type the page draws differently (in another font) keeps the layers, with a warning. A line break inside a paragraph stays a line break in it (`crates/eps/src/import/tests_native.rs`, `crates/eps/src/import/ate.rs`).
+    `.ai` and EPS editing-data import reads a text document whose keys are written by name, as files saved for version 11 write them, and the keys that later files write by name among the numbered ones (a font record's version, a paragraph's direction). The type of such a file comes from its text document, so type outside the artboards opens and each text object keeps its own story A run that names its paragraph or character style by the style's number takes that style (`a_text_document_with_named_keys_gives_type_off_the_page_too`, `a_text_document_with_named_keys_takes_a_runs_style_by_its_number`, `crates/eps/src/import/ate/names.rs`).
     In SVG export without Fewer `<tspan>` Elements, each character of live type that justification or Mojikumi moves (the letter gaps of a Justify All line without word spaces, the gaps between the characters of a justified Japanese line, closed-up punctuation, the space between Japanese and Latin letters) starts its own positioned `<tspan>`, and type scaled horizontally on a justified line is stretched to its own width (`crates/svg/tests/it/text_layout.rs`).
     To find those characters, SVG export lays a type object out a second time only when the second layout can differ from the first: point type with Line-end Punctuation Half Width and no Japanese punctuation or letters, the setting new type gets, is laid out once. Exporting 5,000 such objects takes a median of 109.4 ms instead of 171.5 ms on Windows 11, with the same SVG (`crates/svg/src/export/text/tests.rs`).
     SVG export (live text), legacy `.ai` saves (text objects), DXF export (`TEXT` entities) and the CSS Properties panel write area type that Shrink Text to Fit scales down at the size it draws at, and scale its tracking, kerning, leading and baseline shifts the same way where the format holds them.
