- Interaction editor: actions (top level and inside conditional blocks) reorder by dragging
their row's grip (list_drag, now also for lists shown in model order), one proto.action.move
per drop; the open action stays open where it lands; Escape cancels a row drag without
deselecting or closing what holds the list. The ... menu keeps Move up / Move down.
- Prototype expressions: `accent[Dark]` reads a variable's value in one mode of its collection
(Expr::InMode) and `mode(Theme)` is the name of the mode a collection is in where the
interaction runs (Expr::Mode); parsed, type-checked, displayed, stored by id (names accepted in
JSON), evaluated with the layer's modes. REST import maps VAR_MODE_LOOKUP over a variable and
one of its modes.
- Overlays opened through commands close on a click outside unless told not to, as in the editor.
- Collection::find_mode / current_mode replace repeated lookups.

- Expressions as text: Expr::parse (variables by name, literals, and/or/not, comparisons,
arithmetic, text joins) with plain-English errors, type checks for conditions and set variable
values; display reads back as the same expression.
- New commands proto.action.add/set/remove/move and proto.conditional.addBlock/setCondition/
removeBlock edit single actions by path, inside conditionals too; `expression` text accepted by
these and proto.interaction.add/set.
- Interaction editor: an action list (open, move, remove, add), Add action > Conditional, if /
else if / else blocks with a condition builder (variable picker, operator, value or variable) or
an expression field with inline errors, nested actions, set variable expressions.
- Presenter: hotspot hints toggle (Options menu, proto.presentOptions {hotspotHints}), hotspots from
the engine (proto_run::hotspots) and in ui.inspect; an Inspect panel showing the hovered layer's
properties ({inspect}).
- Fields keep the keyboard on the click that opens them, and the Enter that commits a field no
longer reaches the shortcuts.

- Responsive presentation: `proto.settings {responsive}` (saved in the
page's prototype settings). The player resizes the presented frame to the
device's screen, or without a device to its whole area at 100%, and lays
it out again exactly as an editor resize does (constraints, auto layout,
text; an axis the frame hugs keeps hugging), live as the window, device or
file change. The player keeps its design document and lays the screen out
from it each time (`cmd::proto::respond`). In the presenter's Options menu
(Responsive beside the size options, or Responsive / Fixed size on a
device) and the Prototype panel.
- Device colours: each device model lists its colour variants
(`proto.settings {color}`), drawn in code as the body's band round black
glass; screen corners are masked exactly. Colour picker with swatches in
the Prototype panel.
- Custom size: a bare screen of any size (`proto.settings {width, height}`
picks it), W/H fields and a swap button in the Prototype panel, imported
from REST `CUSTOM` devices.
- Library collections in the Design panel's Variable modes section, under
their library's name (`library.setVariableMode`; copies whose library
isn't read stay listed).
- Flow descriptions in the presenter's flow picker (and its hover) and under
each flow in the Prototype panel.
- Tests in new modules: engine proto_responsive_tests, ui-egui
proto_responsive_tests; REST device test updated.

PDF export
- Vector masks clip to the mask's outline, luminance masks are luminosity
soft masks (alpha masks as before).
- Background blur: the backdrop the page draws under the layer is rendered,
blurred and cut to its shape, under the layer's vector content.
- Text hyperlinks become clickable link annotations (one per line and link).
- Frames-to-PDF shares one path (`frames_pdf`): sRGB conversion for Display
P3 files, hidden frames left out, the file name as the PDF title.
- `figcraft-cli export -o x.pdf` and `convert x.figcraft x.pdf` write the
page's frames one PDF page each.
- Tests: mask types, backdrops, links, image deduplication, page sizes in
points, hostile inputs; CLI end to end. Checked by rendering the PDFs back
to PNG and diffing against the PNG export.
Prototyping
- Model: conditional actions (if / else if / else blocks), set variable mode,
and expressions (literals, variable references, + - * /, comparisons,
and/or/not, negate) for set-variable values and conditions; walk helpers
for nested actions (remap on paste, colours, destination checks, library
copies and pruning, canvas connections).
- REST import maps CONDITIONAL, SET_VARIABLE_MODE and SET_VARIABLE with
variable references and EXPRESSION values; unsupported functions (mode
lookups) skip the action with a warning.
- The presenter runs them in order (`figcraft_engine::proto_run`); the
Prototype panel summarises conditionals, edits set-variable-mode, and
`ui.set {protoEditor}` opens an interaction's editor.

- Device rotation: phones and tablets turn to landscape (`proto.settings {rotation}`), saved in
the file and imported from REST files (`CCW_90`); the presenter and the preview pane size the
screen to the turned device and draw its body turned. A rotate toggle sits beside the device
picker in the Prototype panel.
- Presentation options: fit, fit width, fill and 100% (`proto.presentOptions {scale?,
deviceFrame?}`, an Options menu in the presenter, Z cycles them, R restarts), the device frame
shown or hidden, kept between presentations; what overflows the window pans by wheel or drag.
Presenter textures are capped to the GPU's limit (big frames at 100% no longer overflow it).
- Scroll momentum: drags fling and slow down exactly per frame-rate-independent sub-steps, the
wheel coasts after it stops, a drag past the ends stretches and springs back; repaints only
while moving, a press catches a fling.
- Variable modes in the Design panel: frames pick a mode per multi-mode collection, or Auto
(inherited); `variable.setMode {mode: null}` sets Auto.
- Tests in new modules (engine proto_present_tests, UI present_view_tests); docs and ROADMAP.

* M5: scrolling inside device frames and a prototype preview pane
On a device, the presented top-level frame is sized to the device's screen:
what doesn't fit is clipped, or scrolls (wheel and drag) when its overflow
allows it. Fixed layers stay on screen, pinned to the edges their
constraints name; "Scroll to" moves every scrolling frame around the layer;
navigating starts at the top unless the new "Preserve scroll position"
option keeps it.
The preview pane is a resizable window over the canvas running the same
player (present.rs now shares layout, drawing and input between the
full-window presenter and the pane). It follows edits live, keeps the
current screen while it exists, shows a newly selected top-level frame, and
takes the keys its prototype uses only while hovered. Opened from the play
menu, the Prototype tab (flows, settings, frame) and `proto.preview
{start?}` / `proto.closePreview`; the control channel gets `ui.set
{preview, presentScroll}` and the player's state in `ui.inspect`.
Alt+Cmd+Enter now presents.

- With several layers selected and the same interactions, the Prototype panel edits them all
(add, remove, trigger, action, animation).
- With different interactions it shows "Mixed": + replaces them all with one new click
interaction (one undo step), Remove all clears them.
- New command `proto.interaction.clear {ids?}`.

- Easing gains `customBezier {x1, y1, x2, y2}` (CSS cubic-bezier) and `customSpring {mass,
stiffness, damping}` (a damped spring's step response over its settling time, played over the
interaction's duration); presets keep their string form, so files stay compatible.
- Interaction editor: Custom bezier / Custom spring in the easing menu with value fields (typed or
scrubbed, one undo step), the curve preview follows.
- Presenter: the page's prototype device now frames the presented screen with a body drawn in
code (phones with rounded screens, side buttons and a camera pill; tablets; a laptop with its
base; a desktop monitor on a stand).
