The mark
A lowercase f drawn as one aurora sweep, with an ember held in its curve; the letter is the northern sky over the session light. It ships as full color, bone, ink, black, and white, plus a heavier simplified cut for sizes under 24 pixels.
Wordmark and lockups
The wordmark is Fraunces 400 at optical size 144, SOFT 50, tracked -0.02em, always lowercase, outlined to vectors so it renders without the font. Horizontal is the default lockup; stacked is for centered and square placements. Clearspace equals the ember dot diameter on every side; minimum mark height is 20 pixels, minimum lockup height 28 pixels.
App icon and favicon
The icon sits on the night tile with a faint dusk radial; the simplified mark carries the small sizes. PNG exports live beside the SVGs.
Color
Dusk-indigo grounds, one ember accent, aurora green held for breath and success. The full token table lives in web/DESIGN.md.

Motion
One signature move: the 4.5 second breath pulse, scale 1 to 1.035 with a synced glow swell, applied to a single element at a time. The ambient stage behind the player drifts on the same clock.
