Coastal light & tide journal

The day begins at the waterline.

Foreshore is a quiet record of first light, the turning tide, and what crosses the shallows. Color is rare — warm for the moment that matters, cool for the thing you point to.

How a day reads

Three lights, one meridian

Every day on the foreshore is bracketed by light. The warm moments — first and last — bloom; the cool middle is when the tide turns. The same warm-to-cool line runs through every screen.

01 · Dawn

First light

The melon well rises. You mark the time the sun clears the meridian and log what's already moving on the shallows.

02 · Slack

The turn

Azure marks the precise minute of high water — the cool cue, the exact thing you point to before the ebb begins.

03 · Dusk

Last light

A final warm reading closes the log. The day's strata are sealed and the station rests until the next dawn.

The signature

A horizon of light, not a border

Foreshore never draws a grey line to divide things. Sections, cards and the active tab are separated by a meridian — a thin gradient where warm dawn meets cool dusk, with a soft bloom above it.

It is the only structural mark in the whole language. Where you'd expect an outline, you get a line of light instead.

The current reading warms; everything else stays cool and quiet. No dense grid, no rainbow — just the day's crossings, in order.

From the field

"I used to scribble first light on the back of a chart. Now the whole season reads like one long tide."
