bflatasticandClaude Opus 5.5 e63606826a Fix #508: PDF/.ai import keeps type strokes, wrapped lines and layer order
- Type left unfinished when a layer's marked content ends, and a clip that closes in a later layer,
  stay in their own layer (no stray "Page N" layer, no art moved to the next layer).
- Top-level layers stack as the pages mark them, so a layer whose art starts on a later page keeps its
  place; layers marked with no art come in empty.
- A stroke written as each glyph's outline stroked, right after (or before) the type, becomes the type
  object's stroke above (or below) its characters: the type stays one editable object.
- Spaces read from gaps wider than a space get their own tracking where even tracking would put the
  glyphs after them more than a tenth of an em off (barcode digit groups); lines are measured to their
  last visible glyph, so a wrapped line's trailing space no longer spreads into the tracking.
- Lines wrapped in a frame (each wrapped line ending in a space, one left edge, font, size and leading,
  with an optional paragraph spacing) come back as one area type object, left aligned or justified,
  only where laying it out breaks the lines exactly where the file does.

bflatasticandClaude Opus 5.5 4b6c3d1e2c Fix #319: exports warn when type in a missing font is written in the fallback font
Opening a PDF whose fonts aren't installed keeps the text live in the fallback font (as
Illustrator substitutes and highlights missing fonts), and opening said so, but every export
then wrote the fallback font silently ("warnings": []), so a headless convert re-set the type
without a word.

- Exports that draw type now say so in their warnings, naming the missing families and the
  fallback font: PDF (outlined or real text, also .ai and Save As), EPS, EMF/WMF, raster images
  and SVG with outlined or embedded fonts. Live SVG text, DXF, text and native files name the
  font itself and don't warn. Replacing the font (Find Font) clears it.
- The fonts a document uses (text.fonts' scope, Package's font list) come from one helper.
- textAs: outlines already keeps the glyphs the PDF draws (its embedded font program, installed
  or not): now covered by a test with an embedded serif font that isn't installed, checked
  against the installed font's and the fallback's outlines.
- docs/mcp.md and ROADMAP describe the warning.

bflatasticandClaude Opus 5.5 0687d2d127 Type: Paragraph Direction instead of an Automatic alignment toggle; bidi only where needed (review of #300)
Illustrator sets a paragraph's direction (Left-to-Right / Right-to-Left
Paragraph Direction in the Paragraph panel, with the Middle Eastern
options) and keeps its alignment buttons physical; it has no automatic
alignment toggle. So:

- ParaStyle.direction (None: from each paragraph's first strong
  character, as before; written only when set), the Paragraph panel's two
  direction buttons with Show Indic Options (original icons), and
  text.setFormat {direction: "auto"|"leftToRight"|"rightToLeft"}. The
  layout uses it as the base direction.
- The Automatic alignment check box is gone. Justify::Auto stays as the
  start of the paragraph's direction, set on new type only (text.create,
  the Type tools, with the mojikumi default in one new_type_para()):
  TextObject::point is Left again, so importers (PDF, SVG, DXF, EMF) keep
  their own alignment. The alignment buttons show what Auto resolves to.
- Bidi only where there is something right to left: plain paragraphs skip
  the algorithm (no per-layout allocation), it runs once per paragraph
  (shaping takes the paragraph's levels instead of recomputing them; path
  type computed it four times), and the shaper keeps Han, Hiragana,
  Katakana and Bopomofo in one segment (splitting at every change of
  script cost Japanese text a shaper call per kana-kanji switch).
- Vertical type keeps its logical order, so its glyphs and lines are not
  marked right to left (the caret no longer runs backwards down a column).
- PDF import puts Hebrew and Arabic, which PDFs (and VectorCraft's own
  export) draw in visual order, back in logical order with the direction
  that shows it as drawn; with bidi layout it came back mirrored.
- SVG import pins the direction SVG implies (left to right unless
  direction: rtl); SVG export also outlines right-to-left paragraphs.
- Docs (development.md), ROADMAP (folded into the Type entry, Type core
  row) and README updated; catalog rows for the new labels.

Brandon ThomasandClaude Opus 5.5 5be1790717 PDF import (#337 follow-up): keep missing-font text live, decide each font's face once, Kangxi fix for CID text only
- Text in fonts that aren't installed comes in as live type in the fallback font again, named as
  before (Helvetica-Bold → Helvetica Bold), not outlines plus pink copies on a non-printing layer.
- The installed face that matches a PDF font is decided once per font from its first comparable
  glyph, not per glyph (loading up to 64 faces each time, and switching style mid-line).
- Kangxi radicals are unified only for text from Adobe's CID tables, not ToUnicode maps.
- A line is laid out again only when tracking changed it.
- CidText::of is tested on data that isn't a CID-keyed CFF (embedded fonts are untrusted).
- NOTICE: Adobe CMap resources (BSD-3-Clause) bundled through hayro-cmap.

imachusandClaude Opus 5.5 fcaeaa74a7 PDF/.ai import: Japanese text as live type (CID fonts, vertical columns, missing fonts)
Japanese PDFs and PDF-compatible .ai files often set text in CID fonts
with no ToUnicode map, in vertical columns, and in fonts the reader
doesn't have. They came in as outlines (or as the wrong characters).

- CID fonts without ToUnicode: the character comes from the font's CFF
  charset through the standard CMaps (hayro's `embed-cmaps`); Kangxi
  radicals that some generators map to are unified with their ideographs
  (⿓ → 龍).
- A glyph becomes live type only when the installed font draws the same
  glyph: compared by box with the font of the PDF's PostScript name, or
  the closest style of its family (a variable font's named instances),
  whose style the type then takes. Otherwise it keeps its outline.
- Vertical columns (WMode 1, glyphs with no horizontal advance) come back
  as vertical type, letter spacing as tracking; a single upright glyph is
  vertical type too. Horizontal lines get tracking from the glyph
  positions the same way.
- Text in a font that isn't installed keeps its outlines (what prints),
  with an editable copy in a substitute font, drawn pink, on a
  non-printing layer named after the missing fonts (stroke-only glyphs
  included).
- Marked content other than a layer's (spans with actual text,
  artifacts) no longer ends a line of type: 篳篥・龍笛・笙 came back as
  three objects when one character was in a span.
- Tests in tests_live_text.rs and tests_realtext.rs.
