Subject: [PATCH] Show date on Today/Tomorrow tabs and remove table headings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tabs now display the date (e.g. "Today 2026-02-14"). Removed redundant
"Today — DK1" / "Tomorrow — DK1" headings from the price tables.
