seo: per-post social cards, FAQ schema, month archive, privacy post

- Add scripts/gen-social-cards.js: renders a branded 1200x630 card per blog
  post (title + date on the KashCal template) via rsvg-convert, committed under
  static/img/social/blog/, and re-points each post's og:image to its own card.
  Exposed as `npm run social-cards`. Fixes every post sharing one link preview.
- Add a reusable FaqSchema component and emit FAQPage JSON-LD on the FAQ page
  and the three feature pages with a Common questions section, for FAQ rich
  results.
- Swizzle BlogArchivePage and BlogSidebar/Content to group posts by month
  ("July 2026") instead of year.
- New privacy blog post on KashCal's no-account, no-tracking, offline-first
  design; revives the behind-the-scenes tag.
- Give accessible-calendar-android its own social card instead of the default.
- Put the target keyword in the meta title of calendar-insights and
  share-event-as-card while keeping their evocative on-page H1.

 Your calendar is the nosiest app on your phone. It knows about the dentist, the interview you told nobody about, and the event you just labeled "lunch??". It is a diary that schedules your life.

 For a while now, KashCal has had a quiet flaw: you could only use it by looking at it. It worked beautifully with your eyes, and went silent as a stone the moment you turned on a screen reader. A calendar that only works when you're watching it is, on reflection, a poster. So this release taught it to talk.

 Last release we gave you KashCal Teal and were very pleased with ourselves. Then someone pointed out the obvious: we had spent a whole update letting you choose your color, and then chose it for you. A calendar telling you your favorite color is teal is a bit like a waiter ordering for the table. Bold. Rarely correct.

+---
+
+Most apps greet you with a wall: sign in, or create an account. A calendar app doing that is quietly asking you to route your dentist appointments, your interviews, and your "lunch??" through a stranger's servers so it can hand them back to you later. KashCal never asks. There is no account, because there is nothing to sign into.
+
+{/* truncate */}
+
+## No account, because there are no KashCal servers
+
+This isn't a privacy setting you switch on. It's the shape of the app. There is **no KashCal account** to create, **no KashCal server** anywhere for your events to pass through, and **no analytics, telemetry, or ad SDK** riding along inside. There is, quite literally, nowhere for us to send your data, so there is nothing for us to collect. A privacy policy is easy to write when the honest version is "we don't have your data and never did."
+
+## Your calendar lives on your phone
+
+Your events sit in a [secure database on your device](/docs/privacy/overview) that other apps can't read. The only things that ever leave your phone go to servers **you** chose: your events sync to your own calendar server, iCloud, Nextcloud, Fastmail, or [any CalDAV service](/docs/sync/supported-servers), and an RSVP goes to the organizer who invited you. Nothing else goes anywhere.
+
+And when you're offline, none of that matters. KashCal is [offline-first](/docs/sync/how-sync-works): everything you do lands instantly on the device, and it quietly catches up with your servers when there's a connection. A plane, a basement, a dead zone, the calendar still works.
+
+## Passwords that can't be lifted from a backup
+
+When you connect a calendar server, its password is [encrypted on your device](/docs/privacy/overview) with AES-256, and the key lives in the Android Keystore, hardware-backed where the phone supports it. The key is tied to that one device, so a stolen backup can't be replayed onto another phone to reach your accounts. The trade-off is honest: move to a new phone and you re-enter your passwords. We think that's the right side of the line.
+
+## Permissions you can actually reason about
+
+KashCal asks only for what a feature in front of you needs, and it asks in context, with a plain reason. Contacts is for suggesting guests and showing birthdays. Calendar access is for showing the calendars other apps already keep on your phone. Decline any of it and the rest of the app keeps working. No all-or-nothing gate at the door.
+
+## Free, and open about it
+
+KashCal is free and open source under Apache-2.0, so "we don't track you" isn't a promise you have to take on faith. The source is [right there to read](https://github.com/KashCal/KashCal). If we ever added a tracker, someone would see the commit.
+
+[Get KashCal free on F-Droid](https://f-droid.org/packages/org.onekash.kashcal/). No account, no ads, no catch. Read [how privacy works](/docs/privacy/overview) in full.
+
+Your calendar was never anyone else's business. Now it's built that way.

+<FaqSchema items={[
+  {question: 'Is KashCal free? Is there a catch?', answer: "Yes, it's free and open source under the Apache-2.0 license. There's no paid tier, no ads, and no account to create. A donation is optional and never required, and nothing in the app is locked behind it."},
+  {question: 'Do I need to create a KashCal account?', answer: 'No. KashCal has no accounts and no servers. You connect your own calendar accounts (like iCloud or Nextcloud), and you can use the app fully offline with a local calendar even without connecting anything.'},
+  {question: 'Does KashCal track me or sell my data?', answer: 'No. There is no analytics, no telemetry, and no advertising. Your data stays on your device and your own calendar servers.'},
+  {question: 'Which calendar services does it work with?', answer: 'iCloud and any CalDAV server: Nextcloud, Fastmail, Radicale, Baikal, Zoho, mailbox.org, Stalwart, SOGo, and more.'},
+  {question: 'Does it work with Google Calendar or Outlook?', answer: 'Yes, through your phone. Google removed third-party CalDAV access and Outlook does not expose CalDAV, so both come in through the Device Calendar bridge: if the Google or Outlook app already syncs those calendars to your phone, KashCal shows them.'},
+  {question: 'Is KashCal on the Google Play Store?', answer: 'Not yet. KashCal is distributed through F-Droid, IzzyOnDroid, and Obtainium.'},
+  {question: 'Does KashCal support CardDAV, tasks, or attachments?', answer: 'No. KashCal is events-only (VEVENT). It does not do CardDAV (contacts) or VTODO tasks and attachments. Calendars that contain only VTODO or VJOURNAL resources are skipped during sync.'},
+  {question: 'Why will my iCloud password not work?', answer: 'iCloud requires an app-specific password, not your normal Apple password. Create one at account.apple.com and use that to connect.'},
+  {question: 'Can I use KashCal offline?', answer: 'Yes, it is offline-first. You can view and edit events with no connection, and changes sync automatically when you are back online.'},
+  {question: 'Why is background sync not more frequent than 15 minutes?', answer: 'That is an Android system limit for background work. It is the shortest automatic interval the platform allows. You can always pull down to refresh for an immediate sync.'},
+  {question: 'What Android version do I need?', answer: 'Android 12 or newer.'},
+  {question: 'How do I move to a new phone?', answer: 'Back up your settings, restore them on the new device, and re-add your calendar accounts (passwords are not transferred, by design). Your events come back via sync.'},
