PWA Architecture & Service Worker Lifecycle

Cora ships with native Progressive Web App (PWA) capabilities, offering sub-50ms screen painting and native-like offline reliability.

1. Dynamic PWA Manifest

Served dynamically at /cora-manifest.json:

• display: standalone
• theme_color: #ffffff (Pure Light Mode splash to eliminate dark flashes)
• Dynamic version stamps (?v=CORA_WORKSPACE_VERSION) to trigger immediate OS icon updates on release.

2. Service Worker Lifecycle

Registered at root scope (/):

• Cache-First: Static CSS/JS and font assets.
• Network-First: AJAX actions and REST endpoints with sub-400ms timeout.
• Auto-Activation: skipWaiting() and old version cache purging executed on update.
