frame-cli 0.3.0

/*
 * The page's whole visual shell. `src/main.ts` imports this file, so the
 * build bundles it into dist/ as a hashed asset — nothing here is fetched
 * from anywhere else: system fonts only, no CDNs, works offline.
 *
 * The markup these rules style is rendered by `src/main.ts`. Two kinds of
 * hook exist and they never mix: the ids (#status, #log, #send-form,
 * #send-input) carry behavior and are driven by `scripts/e2e.mjs`; the
 * `data-state` attribute on the status pill and the `data-kind` attribute
 * on each feed row are presentation-only and safe to restyle freely.
