@Rekoo-PS reported that gallery URLs sent via the WhatsApp Business API render an unbranded "PicPeak - Photo Sharing Platform" preview even though manual link sends from the WhatsApp app pick up the per-event rich preview correctly. Two root causes, two fixes: 1. WhatsApp Business and 3rd-party preview services (Twilio, LinkPreview.net, etc.) don't always crawl with the recognisable "WhatsApp/X.Y.Z" UA we matched in nginx + galleryOgService. Extend the regex (both copies) to also catch WhatsAppBot, wa-bot, LinkPreview, and Slack-ImgProxy. 2. Even with broader UA coverage, some senders cache metadata with no UA at all and fetch the static SPA shell. That shell's <title> was hard-coded to "PicPeak - Photo Sharing Platform" — embarrassingly generic for any self-hosted brand. Switch to Vite's %VITE_DEFAULT_TITLE% / %VITE_DEFAULT_DESCRIPTION% HTML substitution so self-hosters can bake their brand into the fallback at build time. Defaults stay "PicPeak" so the upstream image doesn't change behaviour for anyone. The per-event rich preview path (handleGalleryOgRequest, fired on matched crawler UAs) is unchanged — this only improves the fallback for unrecognised UAs and for the SPA-shell title that humans see in their browser tab. Adds a vite.config plugin to provide the defaults when env vars aren't set, so unsubstituted "%VITE_..." literals never reach the built HTML. Adds .env.example entries explaining the override. Tests: extend galleryOgService.shareImage.test.js with an isSocialCrawler suite that pins every documented UA (incl. the new ones) plus three browser UAs (negative) and null/empty edge cases. Verified locally: `vite build` with VITE_DEFAULT_TITLE="MyBrand" produces <title>MyBrand</title> + og:title="MyBrand"; without the env var falls back to "PicPeak". Refs: #521
