Spur was using availH=h (no padding) giving 14px, while conveyors
used availH=h-4 giving 13px. Now both use the same padding.

Previous min() was wrong — pushed text further right when text was
wider than available space. Now uses max() to keep text left-aligned
within the trapezoid while right edge stays at the angled boundary.

Measure actual text width and position so the right side of the text
aligns with the angled edge of the spur, preventing overflow onto
adjacent conveyors.

Position text at 55% height (toward wider area), then center
horizontally based on the actual right edge at the text's top,
minimizing overflow past the angled edge.

The 90-degree corners are at x=0 in local coords. The rectangular
region from x=0 to x=min(w2,w) always fits inside the trapezoid.
Text is centered in this safe zone — on the straight-edge side,
not the angled side.

Shift text toward the bottom-right corner of the trapezoid where
the right angle creates the most open space for the label.

Text centered at x = (w2 + w) / 2 — the middle of the wide right
portion of the trapezoid where there's the most space.

Place text centered at the wide bottom edge where there's always
enough room. No font shrinking — the wide end has plenty of space.

Center text at 75% of trapezoid height where the shape is widest,
using the actual width at that height for proper fit.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

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

- SVG export now embeds layout JSON as HTML comment for re-import
- New loadLayoutSVG() extracts embedded data from exported SVGs
- Import accepts both .json and .svg files
- New exportJSON() saves layout as MCM_layout.json
- JSON export button added to toolbar

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

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.

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.
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

- 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>
- Right-click context menu: "Hide" option to hide individual symbols
- "Show All Hidden" appears in context menu when anything is hidden
- Top visibility bar with toggle chips for each device group
- Hidden symbols are excluded from rendering, hit testing, and SVG export

- Single-element SVGs: id/label/transform directly on the element (no <g>)
- SVGs with <g> group (dpm, diverter): keep the group, put id/label on it
- Multi-child SVGs without group (beacon): wrap in <g> with id/label
- Programmatic shapes (induction, curved, spur): single <path> with id
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add search filter to Devices tab in right dock

- Single resize handle for curves (was 2)
- Add .gitattributes for consistent line endings
