Greptile Summary

This PR reverts #2843 ("Feat green day"), which added an April Fool's green branding theme to the Appwrite website. The revert cleanly restores the default pink brand identity across all 45 changed files.

Key changes undone by this revert:

• Theme switching infrastructure — removes BrandTheme type, applyBrandTheme/getPreferredBrandTheme helpers, localStorage persistence, PUBLIC_BRAND_THEME env var support, and MutationObserver-based class-watching in both Main.svelte and Docs.svelte
• CSS variables for theming — removes --web-color-button-primary, --web-color-brand-rgb, --web-color-image-accent-filter, --web-color-image-background-filter, and all body.brand-green / body.brand-pink overrides; restores hardcoded pink rgba/hsl values in button, badge, card, hero-banner, and side-nav SCSS
• Image tinting CSS — removes the large block of :global(body.brand-green …) CSS filters in +layout.svelte that recolored icons and background images
• Green logos — deletes appwrite-green.svg, appwrite-light-green.svg, and logo-green.svg; restores static logo paths in nav headers
• Brandable wrappers — removes homepage-brandable, products-brandable, docs-brandable, and pricing-brandable container divs used to scope image filters
• mongo icon — removes the MongoDB SVG icon that was added to the sprite sheet for the green day feature

A Grep search confirmed no residual references to brand-green, brand-pink, BrandTheme, brandTheme, the deleted logo files, or any of the removed CSS variables remain anywhere in src/.

Confidence Score: 5/5

• Clean, complete revert with no residual green-theme references — safe to merge
• All 45 files are straightforward reversions of the green day feature. A full-codebase search confirmed zero remaining references to brand-green classes, the removed CSS variables, deleted SVG logos, or brand-switching logic. No new logic was introduced — only removals and restoration of prior hardcoded values.
• No files require special attention
