Aldus 1.17.0

• Pack data is now lazy-loaded — it only downloads when you open the Browse Styles tab, reducing the initial bundle by ~40 KB and speeding up block load times on shared hosting.
• PHP files are now loaded conditionally by request type: front-end page loads that don't contain an Aldus block skip the full renderer stack, saving ~1-2 ms per request on high-traffic sites.
• Storage quota exceeded (common on mobile and restricted corporate environments when the AI model download fills browser storage) now shows a clear error message explaining what happened and how to resolve it.
• The onboarding flag is now stored in the WordPress Preferences API (core/preferences store) instead of browser localStorage, so it follows the user across devices and sessions.
• Usage statistics are now stored as a single consolidated option instead of one database row per layout style, reducing wp_options table bloat on busy sites.
• The plugin's stats (total layouts generated, most-used style) are now visible in Tools → Site Health → Info, making it easier to diagnose issues from support tickets.
• The fallback layout renderer now uses serialize_block() to produce canonical WordPress block markup, preventing subtle validation differences that could cause block warnings.
• WordPress 6.7+ sites automatically use the new block metadata collection API for faster block registration.
• The REST endpoint for layout assembly now validates Content-Type (must be application/json), preventing edge cases where form-encoded data was accepted.
• Assembly timing is now returned in the API response and logged in the browser console under window.aldusDebug for performance diagnostics.
• Error counts are now tracked per layout style and exposed via the GET /aldus/v1/health endpoint, making it easier to identify which styles have reliability issues.
• The health endpoint (GET /aldus/v1/health) now returns plugin version, PHP/WP versions, object cache status, palette size, and per-style error rates.
• Uninstalling the plugin now removes all transients, post meta, user meta, and usage counters — no database residue left behind.
• Theme data cache is now flushed when a theme is updated via the WordPress admin (upgrader_process_complete hook), preventing stale palette colours after a theme update.
• The content/preview tab toggle in the editor now uses the core TabPanel component, with proper ARIA roles and keyboard navigation.
• The admin welcome page styles are now enqueued as a stylesheet via admin_enqueue_scripts instead of inline style attributes, improving CSP compatibility.
• Fixed a regression where spacingSizes injected via the theme.json filter were silently lost in certain WordPress versions (6.4, 6.7) due to preset origin-tracking in WP_Theme_JSON::merge().
• Fixed constant redefinition warnings in the integration test bootstrap.
• Fixed PHPUnit 9.6 / PHPUnit 10 schema mismatch in phpunit-integration.xml.dist.
