The system

The tokens, the three type roles, the reworked controls, and the rule every figure on this site obeys.

palette

Six values, every pair verified against the ground it sits on

The ratios below are computed at render time from the tokens themselves. If a token moves and a pair drops under AA, this table reports the failure rather than hiding it.

ink#0C1512

Deep ground. Undergrowth green-black, never pure black.

bark#1A2620

Raised surfaces: cards, panels, the footer.

ridge#1F2C25

Second elevation: inputs, table headers, active rows.

fletch-core is graphic-only — its AA-large rating is correct for fills and strokes, and it is never used for type

A strategy is a function of a timestamped market state and a set of parameters onto a decision. The replay is exact, not statistical: we compare a hash, not an overlap rate.

Verification cost is close to zero for pure artifacts. The statistical fallback is reserved for artifacts that call an LLM, and it is priced into that artifact’s fee.

the hard rule

Every number on this site is set in tabular mono, right-aligned in tables, with the unit in chalk at 0.75em

There is no way to type a number as free text in a component. Figures go through a single primitive that owns the formatting, the alignment and the accessible label.

Past 0.85 the figure turns to the action accent — the one place the colour is allowed to appear outside release and deny.

formulas

The formulas are the product

KaTeX, retuned to the palette, on a plate that names the quantity it computes. Inline too: congestion is $u = C_{\text{subscribed}} / c_{\max}$ and it is what the target rings encode.

§9.3 · access price under congestion

p(u) = \frac{p_0}{(1-u)^{\gamma}}

The price of a capacity slice diverges as the sleeve fills. γ is governable within ±50%.

§8.4 · performance fee from the Shapley value

F_i = \kappa_i \cdot \varphi_i^{+} \cdot \mathbf{1}\{W_e > \mathrm{HWM}\} \cdot \min\!\left(1, \frac{\Pi_e^{+}}{\sum_j \varphi_j^{+}}\right)

Three guardrails in one line: netting, the high-water mark, and the negative epoch where nobody collects.

motion & scenery

motion-primitives, Watermelon and haikei, retuned

Every spring on the site is one of four stiffnesses — the marks in the gutter. Under prefers-reduced-motion none of them run: figures render at rest, the lamp never lights, the tape stands still and scrolls by hand.

the lamp and the needle

counts in view · k = 76

figure: the spring runs the raw quantity through formatValue — never a second typographic object
magnetic: 0.24 of the pointer offset, mouse only, released on leave
spotlight: brass lamplight pooled under the pointer; hover this panel
gauge: the header hairline is the one always-on instrument

haikei, redrawn into the grounds

layered waves · the footer strata

contours · section heads, the hero, the 404

peaks · the sentinel's far ridge

Fills are mixed between ink and bark, strokes are brass, and all three are static SVG: nothing to reduce, nothing to load, and they survive with JavaScript disabled.
