Report styles and assets

HELIA tokens.css and semantic.css are derived from helia-ui v0.1.0-alpha.26.
The font-face declarations were removed so reports use system fonts offline.
The upstream BSD-3-Clause license is in HELIA-UI-LICENSE.txt and included in
reports. report.css and report.js implement the model-report presentation.

The Ambiq blue and white SVGs are unchanged copies of the official assets
served by the heliaAOT documentation site:
https://ambiqai.github.io/helia-aot/_astro/ambiq-logo.BEwJzeCh.svg
https://ambiqai.github.io/helia-aot/_astro/ambiq-logo-white.YScGqFHI.svg

helia-aot-icon.svg is a seven-hexagon recreation of the official heliaAOT PNG,
rendered monochrome in the report header. It is not an upstream vector asset.
