Center text at 75% of trapezoid height where the shape is widest,
using the actual width at that height for proper fit.

Center text at vertical midpoint, shifted right toward the wider end
where there's more horizontal space. Uses 55% of the mid-height width
as center position and 85% as available width.

- Move text to 65% from top (wider end) so it fits without shrinking
- Fix effective angle for mirrored symbols: use (360-rot) to determine
if flip is needed, preventing incorrect upside-down detection

Position text at 40% from top (toward narrow end) and constrain width
to the narrower edge so text never overflows the trapezoid shape.

Mirrored symbols need text counter-mirrored (scale -1,1) to prevent
backwards text. Restored mirror fix that was incorrectly removed.
Applied to both canvas renderer and SVG export.

Ignition strips font-weight/font-family/font-size as separate SVG
attributes but preserves them inside style="..." CSS. Moved all text
styling to inline style for conveyance labels and BCN/SOL/PDP symbols.

Replace dominant-baseline="central" (unsupported in Ignition) with
manual y offset (10 -> 12.8) for proper vertical centering of text
inside these symbol boxes.

Labels now follow the mirrored shape naturally — text mirrors
along with the conveyor/shape as the user expects.

Canvas renderer:
- Straight/spur: flip text 180 when rotation is 91-269 deg
- Mirror: counter-scale text so it doesn't read backwards
- Curved: compute world angle (sym rotation + tangent), flip if upside-down
SVG export:
- Curved text now includes rotation transform along the arc tangent
- Straight text includes rotation correction for readability
- All text stays grouped with its shape for proper transform inheritance
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Wrap each conveyance shape + its label text in a <g> element so
rotation/mirror transforms apply to both shape and text together
- Change stroke-width from 0.5 to 1 on all conveyance and PE shapes
(both canvas renderer and SVG export)
- Text is now inside the group, inheriting the transform — no more
floating unrotated labels

Ignition strips SVG transforms from text elements, causing labels to
float to wrong positions. Now all text uses pre-computed absolute x/y
coordinates without any transform attributes. Also fixes positioning
for curved (at arc midpoint), spur (trapezoid center), and induction
(strip center) symbols.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Curved: position at arc midpoint with rotation along curve
- Spur: center in trapezoid shape, not bounding box
- All: use dy offset instead of dominant-baseline for reliable centering
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Curved: position text at arc band midpoint, rotated along the curve
- Spur: center text in the trapezoid shape, not the bounding box

isTypeCompatible now matches by conveyance family, not just SVG file.
Conveyor family includes: conveyor, spur, curved_conv, induction, extendo.
Chute family includes: chute, tipper, curved_chute.

Parse labels like UL17_22_VFD into stacked text: "UL" / "17-22".
Bold black Arial, targets 14px but auto-scales down to fit with
consistent padding. Strips _VFD suffix, splits prefix from numbers.
If full text doesn't fit, strips the letter prefix.

- Fix shift-drag: require 8px movement before locking axis, use strict
greater-than to avoid horizontal bias at small deltas
- Add PE shape-following outline for selection/hover/collision highlights
- Add PE shape-aware hit-testing (arrow + beam + receiver zones with margin)

The axis constraint was recalculated every mouse move, causing the symbol
to jerk between horizontal and vertical near the 45-degree diagonal.
Now the axis locks on first movement and stays locked until shift is released.

Also add previous 30x14 default to migration table so existing
PEs at either old size get updated on load.

Split SVG export into two passes: base conveyance symbols first, then
overlay devices rendered last so they appear on top in the exported SVG.

Replaces embedded SVG export (which used non-uniform scale transforms
that stretched strokes) with programmatic path/rect elements matching
the canvas renderer. Consistent 0.5px stroke at any size.

When loading saved state, symbols with known outdated default sizes
(e.g., photoeye 56x20) are migrated to current defaults (30x14).
Only exact matches of old defaults are migrated — user-resized
symbols keep their custom dimensions.

SVG-based rendering caused non-uniform stroke scaling when symbols were
stretched. Now conveyor, chute, tipper are drawn as canvas rects, and
extendo is drawn as a canvas path with fixed left bracket proportions.
All use consistent 0.5px stroke regardless of size.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Change all conveyance SVGs from black fill to white fill with black stroke
- Update programmatic rendering (curves, induction, spur) to white fill
- Replace PE 3-slice rendering with programmatic canvas paths for
consistent stroke width at any size
- Reduce PE default size from 56x20 to 30x14 to fit around conveyor devices
- Update SVG export to match new white fills

Rotate the direction vector -90° for the right box in collision
detection and bounds calculation to match the perpendicular
rendering orientation.

- Right box stroke now uses EPC_CONFIG.lineWidth (1.5) instead of 0.3
- Right box positioned at -rb.w (backward) matching canvas renderer
- End box rotated 90° (perpendicular to line) in canvas, export, and hit-testing
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replace bounding-box hit test with proper shape-aware check that tests
proximity to line segments and oriented end boxes with 8px hit margin,
making the thin EPC much easier to select and drag.

Just expand w/h to cover the full waypoint extent without moving
sym.x/y. The origin-shifting math was causing the symbol to jump
in the direction of waypoint movement on mouse release.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
recalcEpcBounds now properly normalizes the bounding box to start at
(0,0) in local space, adjusting sym.x/y to compensate so the world
position and rotation center stay constant. Handles rotated symbols
by rotating the center offset into world space.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Updating sym.w/h mid-drag shifted the rotation center used by
toSymbolLocal, causing waypoints to jump. Now recalcEpcBounds
only runs on mouseup, keeping the coordinate transform stable.
Also removed the endpoint slide constraint that was causing
instability due to using the moving position as direction source.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- First/last waypoints now only extend/shorten along their segment direction,
preventing unwanted rotation of the end boxes
- Middle waypoints remain freely draggable for direction changes
- Add default middle waypoint so new EPCs have 3 control points
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Increase EPC line width from 0.4 to 1.5 for visibility
- Increase right box stroke from 0.3 to 1.0 to match left icon stroke
- Fix right box to extend behind last waypoint (like left icon), not forward

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Reduced font sizes and used dominant-baseline="central" with y at

Collision detection now mirrors spur trapezoid and induction arrow
vertices when the symbol is mirrored, matching the visual appearance.
Previously the collision polygon stayed unmirrored causing false
positives/misaligned collision zones.
