// The console's icon set — every piece of interface chrome, one file. This
// is the server-side twin of Eleven's web/static/icons.js: static, in-code
// SVG strings in the Lucide idiom (24×24 viewBox, currentColor, stroke, round
// caps and joins), inlined into the page at render time.
//
// Vendored, never a CDN. The console has the same hard constraint as the
// fleet status page — no build step, no JavaScript framework, and no external
// request, ever. A <script src> or <link href> at some icon host would be a
// second origin the console cannot vouch for, cannot cache-control, and
// cannot serve when it is offline. Inlining the paths is the only option, so
// the paths live here.

// Emoji policy, inherited from Eleven's docs/icons.md: emoji are CONTENT — a
// mark a person or a model chose, like the footer's factor-X disclosure — and
// never chrome. Interface furniture uses these icons. Adding one = paste the
// Lucide SVG's paths in below, keep the (Lucide: <slug>) comment, register it
// in the icons map, use it as {{icon "<slug>"}}.
//
// Each icon carries aria-hidden="true" because every one of them sits beside
// its own text label — the label is the accessible name, and a second one
// from the icon would only be read out twice. An icon used as the ONLY label
// must not use these constants bare: give its button or link an aria-label.

// from those sources must stay a plain string so html/template escapes it —
