Nearest tide and current stations, an endless timeline, and sharing

Finding the right station, a timeline that doesn't end, and sharing the moment you're looking at.

• My Location shows two cards — the nearest tide station and the nearest current station — and Near Me and search share All/Tides/Currents filter chips. Every tide detail links to the nearest current station and back again, with the distance in the label.
• The detail timeline scrolls without end in both directions. Tapping anywhere on it brings that moment to the centerline; a sunrise or sunset scrubs to itself, and the date opens the week picker.
• A share button sits beside the star on every detail page. It sends a slackwater.xyz link, carrying the instant you scrubbed to rather than making the receiver find it again.
• The commentary pill names sunrise or sunset whenever it comes before the next high, low or slack — and taps through to it like any other stop.
• The Moon sheet is drawn instead of tabulated: rise and set on a horizon, next full and next new as the discs they name, the orbit under the distance readout, and each eclipse row drawing its own eclipse.
• Shape-only gates such as Malibu Rapids now use the same curve language as measured currents without implying a speed, slack windows read cleanly against the curve, and the card and widget direction arrows match the detail page.
• The schedule collapses to one day at a time, Recents use the same cards as the rest of the list, day labels sit at the middle of daylight rather than clock noon, and the lead readout carries the date while you scrub through the night.
• The station list renders before the catalogs finish decoding, so the first frame arrives sooner.
• Fixes: a My Location card opens the station you tapped, not its neighbour; the location refreshes when the app comes back from the background instead of only on a cold launch.
