bherbruckandClaude Opus 5.5 bd8e8c4809 Web: the viewport shader compiles in browsers (a new design no longer shows a black screen) 
Fixes #34

The surface-analysis curvature map took screen-space derivatives (dpdx/dpdy) inside a branch
of fs_solid. naga accepts that, but browsers' WGSL compiler (Tint, WebGPU) requires derivatives
in uniform control flow and rejects the whole `sc_viewport` shader module, so every viewport
pipeline was invalid and the viewport stayed black as soon as a design was shown. The
curvature is now worked out first thing in fs_solid and passed in, and the canvas image
shader samples its texture before discarding.

Regression test: every fragment entry point makes derivative and implicit-LOD sampling calls
(directly or through helpers) before any branch or return. Checked in headless Chromium with
WebGPU (SwiftShader): before, "dpdx must only be called from uniform control flow" and invalid
pipelines on New Design; after, no shader or pipeline errors.

bherbruckandClaude Opus 5.5 940c425316 Accessibility Analysis: faces a tool coming along a direction reaches (facing it, nothing above: a depth map of the model seen from that direction, tested per pixel on the GPU) shade green, the rest red; the analyses (zebra, draft, curvature map, environment map, accessibility, minimum radius, isocurves, curvature comb, center of mass) also on SOLID INSPECT, and Interference on sketch INSPECT; path patterns follow 3D sketch curves through the same path chain as sweeps (path_segments_3d folded into path_points)
