-        <p>
-          BincioActivity is a free, open-source platform for tracking your outdoor activities —
-          cycling, running, hiking, and more. It is designed to be self-hosted: you (or someone
-          you trust) run the server, and your data stays under your control.
-        </p>
-        <p class="mt-2">
-          Activities are stored in an open JSON format called BAS (BincioActivity Schema),
-          which is designed to be readable and portable. The platform has no hidden analytics,
-          no advertising, and no third-party data sharing.
-        </p>
-      </section>
-
-      <section>
-        <h2 class="text-base font-semibold text-white mb-2">Joining &amp; invitations</h2>
-        <p>
-          This instance is invite-only. To join, you need an invite link from an existing
-          member — each link is single-use and tied to a unique code.
-        </p>
-        <p class="mt-2">
-          Once you have an account, you can generate up to <strong class="text-zinc-300">3 invite links</strong> to
-          share with people you trust. You can manage your invites from the <a id="invites-link" href="invites/" class="text-blue-400 hover:text-blue-300 transition-colors">invites page</a>
-          (requires login).

-      <section>
-        <h2 class="text-base font-semibold text-white mb-2">Your data on this server</h2>
-        <p>
-          When you upload a FIT, GPX, or TCX file, the server converts it to BAS format.
-          By default the original source file is also kept in your account's
-          <code class="text-zinc-300 bg-zinc-800 px-1 rounded">originals/</code> folder.
-          You can opt out of this at upload time by unchecking <em>"Keep original file on server"</em>.
-        </p>
-        <p class="mt-2">
-          Keeping originals is recommended during these early stages of the project: if the
-          processing pipeline improves (better elevation smoothing, speed calculation, lap
-          detection, etc.) you can re-import your files to take advantage of the changes.
-          If you chose not to keep originals, you would need to upload the files again manually.
-        </p>
-        <p class="mt-2">
-          When syncing from Strava, the raw activity data fetched from the Strava API can
-          similarly be stored locally. This is controlled by an instance-wide setting
-          configured by the server operator.
-        </p>
-      </section>

-      <section>
-        <h2 class="text-base font-semibold text-white mb-2">Early-stage software</h2>
-        <p>
-          BincioActivity is under active development. The data format, processing pipeline,
-          and server API may change between versions. Breaking changes are possible, especially
-          at this stage. When they occur, re-importing your original files is the safest way
-          to bring your data up to date.
-        </p>
-        <p class="mt-2">
-          There is no guarantee of uptime, data integrity, or forward compatibility for
-          any particular version. Use this software at your own risk, and keep your own
-          backups of important data.

+          <p>
+            BincioActivity is a free, open-source platform for tracking your outdoor activities —
+            cycling, running, hiking, and more. It is designed to be self-hosted: you (or someone
+            you trust) run the server, and your data stays under your control.
+          </p>
+          <p class="mt-2">
+            Activities are stored in an open JSON format called BAS (BincioActivity Schema),
+            which is designed to be readable and portable. The platform has no hidden analytics,
+            no advertising, and no third-party data sharing.
+          </p>
+        </section>

+        <section>
+          <h2 class="text-base font-semibold text-white mb-2">Joining &amp; invitations</h2>
+          <p>
+            This instance is invite-only. To join, you need an invite link from an existing
+            member — each link is single-use and tied to a unique code.
+          </p>
+          <p class="mt-2">
+            Once you have an account, you can generate up to <strong class="text-zinc-300">3 invite links</strong> to
+            share with people you trust. You can manage your invites from the
+            <a href="/invites/" class="text-blue-400 hover:text-blue-300 transition-colors">invites page</a>.

+          <h2 class="text-base font-semibold text-white mb-2">Your data on this server</h2>
+          <p>
+            When you upload a FIT, GPX, or TCX file, the server converts it to BAS format.
+            By default the original source file is also kept in your account's
+            <code class="text-zinc-300 bg-zinc-800 px-1 rounded">originals/</code> folder.
+            You can opt out of this at upload time by unchecking <em>"Keep original file on server"</em>.
+          </p>
+          <p class="mt-2">
+            Keeping originals is recommended during these early stages of the project: if the
+            processing pipeline improves (better elevation smoothing, speed calculation, lap
+            detection, etc.) you can re-import your files to take advantage of the changes.
+          </p>

+          <h2 class="text-base font-semibold text-white mb-2">Early-stage software</h2>
+          <p>
+            BincioActivity is under active development. The data format, processing pipeline,
+            and server API may change between versions. Breaking changes are possible, especially
+            at this stage. When they occur, re-importing your original files is the safest way
+            to bring your data up to date.
