`init -490 screen`, `import x as y` and `from m import A as B`, classes with @renpy.pure, pickle hooks
on classes, `*` items in tuples and lists, generator functions (yield statements; the player runs them
to the end), multi-line expressions that need brackets, Null() and Animation() images, images given as
expressions (`"path/{}.png".format(x)`, f-strings), window statements in init, `offset` in ATL, input
widgets with their values and the focus/confirm actions, `continue` and `break` in screens, `drag`
and DiamondBox-style `fixed` with cell_size, `getattr(...)()` calls, transforms called with arguments,
and the whitelist for the new runtime. JSON files of a game are shipped as data files. Also fixes
blocking_names failing on a call of a call during full conversion.

The build (fingerprint of its scripts) skips third-party code written against Ren'Py's render API
(colour picker demo, Kinetic Text Tags, cps_preview) and waives its one missing test screen. Converter:
xpan/ypan/matrixtransform/matrixanchor are skipped like other GPU hints, `if renpy.has_live2d()` in an
init block keeps only its else branch, `crop(...)xpos` and `crop (1, 2, 3, 4)` parse, `drag` is a screen
container, `at icon["at"]` becomes a dynamic entry, and the whitelist gains Matrix, Move, absolute and
the no-op helpers. The game now passes the strict check and converts fully (3272 files, 288 MB).

ATL: `ease(1.0) zoom 1.3`, `ease (0.1)xpos 0.5`, `ease(0.1)rotate 5` and `pause(1.5)` take the duration
in brackets; `offset (x, y)` becomes xoffset/yoffset; lines starting with shader, mesh, u_*, blend or
transform_anchor are skipped as GPU hints. thelewdesthouse drops from about 1400 to 111 rejections.
Screens: `for x index k in seq`, `add"x"` without a space, and `onlayer name` after show/call screen
(the layer is ignored, every screen lives in one layer). Transforms named with a capital letter and
declared in another file are resolved by the prescan, and `__("Name") "text"` is a translatable speaker.

`frame at (a if cond else b)` is kept as a choice that the player resolves each time the screen is
drawn. An ATL line splits at top-level commas into separate statements, so `zoom 1.2, 0.2` is a zoom
followed by a 0.2s pause, as Ren'Py compiles it (two-value properties such as `pos 0.5, 0.5` stay
whole). The inert events deselected/unselected, which Ren'Py never sends, are accepted. With the
build profile for The Only Doe 0.05 the game now passes the strict script check.

ATL
- Image blocks become timelines: picture steps with dissolve, parallel, contains,
finite repeat, time, function f(trans, st, at), calls of other transforms with
arguments, on hover/idle events for buttons. Animations stop when their element
leaves the page
- Pictures defined by an expression (get_face_path("base")) are drawn at show time
- Purely graphical hints (shader, mesh, gl_*, u_*) are accepted and dropped
Colour
- matrixcolor and im.matrix.* as 5x5 matrices combined with `*`, applied through SVG
filters; im.MatrixColor/Scale/Crop/Blur/Composite and Text/Image as values
Python
- match statement, re/copy/time/datetime/defaultdict/functools.partial, more
str/dict methods, Character(...) created by code
- narrator("..."), Character calls, renpy.say and renpy.show/hide with expressions in
Python blocks become script nodes
- Audit follows reachability: functions and classes nothing refers to (custom
statement lexers, unused tools) no longer block an import
Docs: README and ARCHITECTURE now describe a multi-engine library (GameMaker and
QSP planned). Tests for the new runtime pieces.

Converter
- screens.py parses the screen language: containers (fixed, frame, vbox, hbox,
grid, vpgrid, viewport, button, has), widgets (text, textbutton, imagebutton,
add, bar ...), if/for/use/transclude, default, python, key, timer, on, inline ATL,
conditional properties, and decompiled forms (unparenthesised operators,
glued property values, comma separated actions)
- style statements, call/show/hide screen operators and Python-level
renpy.show_screen are translated; only screens the game shows are audited,
unused stock screens no longer block an import; undefined screens do
- ATL values may be computed at run time and transforms take parameters
(at blink(0.2, 0.3)); blur property
Player
- screens.ts builds the DOM from the IR and rebuilds it on state changes;
buttons with idle/hover/selected/insensitive states, tooltips, sounds, modal
screens, timers and keys that survive re-rendering, saved with the save file
- Actions: Jump, Call, Return, SetVariable, Toggle*, SetScreenVariable, Show, Hide,
ToggleScreen, Function, Play, Notify, If, Language, ShowMenu, OpenURL ...
- Crop/LiveCrop/Solid/Frame/Transform/DynamicDisplayable values, crop property,
globals(), renpy.variant/change_language/seen_image, transition stubs
Tests: screen parser and runtime (linkedom DOM), screens fixture compiled from
tests/fixtures/screens.rpy. Docs: docs/SCREENS.md.
Twisted-Thoughts now passes the strict compatibility check.

- Unsupported ATL constructs in a transform now block the import only when the
transform is used (at clause, another transform, even before its definition).
Stock screens.rpy transforms for unused screens no longer fail games
- image blocks with one picture plus linear/ease/parallel/repeat keep their
animation (image-level ATL); the renderer also starts it
- Python: skip @gui.variant/@renpy.variant functions (inactive variants), treat
@renpy.pure as transparent, read renpy.store.x as x
- Accept renpy.transition, end_replay, block_rollback and music set_pause/set_pan
as presentation-only no-ops, and implement them in the player (set_pause and
set_pan were allowed by the converter but missing at runtime)
- Skip the 0x52-URM add-on directory (in-game console / save editor) when
parsing scripts and media
- Tests for lazy ATL warnings, moving images and variants

Python sandbox
- try/except/else/finally, raise (incl. re-raise), assert, for/while ... else
- Multi-generator and dict comprehensions
- Builtin exception hierarchy; user exceptions subclass it
- Inside try, missing keys/indexes, division by zero, attribute access on None
and unknown names raise Python exceptions; lookups stay lenient elsewhere
- int()/float() raise ValueError on non-numeric strings
ATL
- converter/atl.py: set/move (linear, ease, easein, easeout), pause, repeat,
parallel, choice, block, on show/hide and named transforms become a timeline
shipped as game.json "atl"; Move() becomes a linear slide
- player/atl.ts: timeline runner wired into the renderer; `on hide` plays
before the picture is removed
- function, time, contains, matrixcolor and expressions still block the import
Tests: exceptions/ATL fixtures and runtime tests, converter ATL tests; README
and ARCHITECTURE updated.
