/* ========================================================================== TEND — design tokens -------------------------------------------------------------------------- The visual language is deliberately the house style of the reference build: chunky 1.6px borders, hard (un-blurred) offset shadows, generous 12–18px radii, and a pixel display face (Pixelify Sans) sitting on top of a plain system sans for body copy. Two themes (light / dark) driven by [data-theme] on , plus one extra switch: [data-candles] flips the up/down colour convention. -------------------------------------------------------------------------- THE PALETTE IS MONOCHROME -------------------------------------------------------------------------- Black and white only, taken from the mark: a white glyph on a black tile. There is no brand hue to lean on, so the design carries hierarchy with LUMINANCE instead of colour, and the rules are: 1. The accent IS the ink. A solid white fill is the loudest thing this palette can do, so it is reserved for the one action that matters — "Launch a coin" — and for the current nav item. Everything else is a border, a hairline, or a shade of the surface. 2. "On chain" and "in your currency" are separated by contrast, not hue. `--accent` (white) is the chain: filled, loud, immediate. `--local` (mid grey) is the money that has been made local: outlined, quieter, set in the mono face. The product thesis survives the loss of colour — crypto is bright, tender is what you can actually spend. 3. `--up` / `--down` are the ONLY chromatic values left, and they are data, not chrome: a green tick means the same thing on every exchange in the world, and a red one means a failed validation. Recolouring them grey would make the market columns unreadable, which is a worse outcome than a monochrome page having two functional colours. `--seg-1 … --seg-8` is the greyscale ramp for chart segments and pie slices, ordered brightest to darkest so a series reads in the same order in both themes. ========================================================================== */ /* -------------------------------------------------------------------------- DARK — the default.
