Per user: lowercase masthead to echo the logo's character (kept as text, not an
image — email clients strip SVG and block remote images, so text always renders
and degrades gracefully). More breathing room before the 'Good morning' intro,
and a horizontal divider after it to match the item separators. (Real logo PNG
remains an option if wanted.)

Per user feedback: rename from 'Today's good news' (which implied the site was
done for the day) to a publication-style 'Upbeat Bytes — Daily Highlights'
masthead with a warm morning intro and a sign-off that links back to the site
('more good news is always waiting'). Adds 'why it's here' to the plain-text
part too. No images by design (lightweight, mail-client-safe).

* On-site end-cap now says "You're caught up for now." — honest, since Highlights
refreshes through the day (the email keeps the daily "see you tomorrow").
* Anonymous "Get tomorrow's brief by email" now honors the one-tap promise:
sets a pending flag, opens sign-in, and auto-enables once auth resolves.
* Email compliance (RFC 2369/8058): send_email takes optional headers; the digest
sets List-Unsubscribe + List-Unsubscribe-Post=One-Click, and a POST
/api/digest/unsubscribe handles native one-click (GET still serves the page).
