    <title>agentLauncher</title>

    <!-- The launch screen. It has to live in the HTML, because #app is empty until
         main.ts has hydrated the launcher config from ~/.agentlauncher/ (two Tauri
         calls) and, in dev, until the stylesheet has been injected by the module
         graph — nothing Vue owns can paint that stretch. Four jobs:

         1. Paint the right canvas colour on the very first frame, from a
            localStorage cache theme.ts keeps for exactly this (fallback: Prism
            Void, the default theme), so a light theme does not flash dark either.
         2. Show a real progress bar, the way a game launcher does: the fill is
            pushed by src/lib/boot.ts as each startup step lands, and the stripes
            keep moving in between so the bar is never a still object.
         3. Stay on screen a beat (see MIN_MS in boot.ts) — an animation that only
            appears on a slow machine is one nobody ever sees.
         4. Hand over softly. #boot is an overlay, not a child of #app, so the UI
            fades in underneath it while it fades out. Without that the app arrives
            in one hard cut.

         No text is baked in here: the status line is filled by boot.ts, which knows
         the locale (agentlauncher.locale, the same first-paint cache i18n keeps). -->
