/* The Signal — weekly feed page (dimsylaisolutions.com/signal/). Layers on style.css: same tokens,
   same doc shell as the legal pages, plus the issue + tile grammar. Tiles are native <details>
   elements — click-to-open, keyboard accessible, and fully readable with JS disabled. Color is
   starlight only: severity dots reuse the stellar tints, "we patched" entries take Scout's green. */

/* The hub's content column (1040px, see index.html .wrap) rather than the 720px legal-page measure: CJ
   reads at reduced browser zoom, so the feed fills the page like the product panels do. Prose inside a
   tile keeps its own 64ch/60ch measure for readability. */
