- Line 197: Update the caller around toHexColor so the resolved variable alpha
value.a is multiplied by solidFill.opacity before conversion, producing the
combined alpha in the hex color. Add a regression test covering variable alpha
0.5 with paint opacity 0.5 and expect the resulting alpha to be 0x40.

…esolution A bound variable's resolved value can carry its own alpha (e.g. a "White 50%" token) separate from the paint's opacity. resolveBoundColor was dropping value.a and using solidFill.opacity alone, so a translucent token on a fully-opaque paint round-tripped as opaque -- a false style mismatch (or false pass) for any contract using such a token. Found by CodeRabbit review on #47.

- Around line 204-206: Update isRgba to require finite numeric r, g, and b
channels, and accept a only when it is absent or finite and numeric. Ensure
malformed RGBA values are rejected so toHexColor uses the literal paint
fallback, and add coverage for missing, non-numeric, and non-finite channels.

isRgba only checked for the presence of an "r" key, so a variable value missing g/b, or with a non-numeric/non-finite channel, would pass through to toHexColor and produce a garbage hex string (e.g. toHexChannel(undefined) rounds to "NaN" and gets embedded verbatim) instead of falling back to the fill's literal color. Found by CodeRabbit review on #47.
extractFigmaStyle previously ignored SolidPaint.boundVariables.color and always compared against the stale literal fill value, so any node whose fill is bound to a Figma Variable (increasingly the default in modern Figma files) produced false positives/negatives in the style gate. Fetching the resolution needs the variables/local endpoint, which is Enterprise-plan-gated on Figma's side, so fetch-baseline only calls it when a node's fill actually carries a bound color id, and treats a fetch failure (403, other HTTP error, deleted variable, non-COLOR variable, unresolved alias chain) as non-fatal: it warns and falls back to the literal paint color, same as today's behavior. Mode resolution uses the node's own explicitVariableModes when present, else the collection's defaultModeId -- ancestor-level mode overrides aren't visible from a single fetched node, a documented limitation rather than a silent wrong answer. Scoping: no contract or fixture in this repo currently uses a bound color variable, so the real-world impact here is zero-cost by construction (the extra API call only fires when a bound color is actually present). Closes #37

Summary
extractFigmaStyle(packages/verify/src/figma-node-style.ts) previously ignoredSolidPaint.boundVariables.colorand always compared against the resolved-at-fetch-time literal fill value. Any node whose fill is bound to a Figma Variable — increasingly the default in modern, design-system-driven Figma files — got compared against a stale/wrong color, producing silent false positives/negatives in the style gate.boundVariables.colorto the variable's current value viaGET /v1/files/:file_key/variables/local, using the node's ownexplicitVariableModesoverride when present, else the collection'sdefaultModeId. Ancestor-level mode overrides aren't visible from a single fetched node — documented limitation, not a silent wrong answer.fetch-baseline.tsonly calls it when a node's fill actually carries a bound color id (boundColorVariableId) — zero extra API calls for the common case.COLORvariable, unresolved alias chain, missingvariablespayload) falls back gracefully to the literal paint color and surfaces a warning, never a thrown error or silently wrong data.Scoping note
Grepped this repo for existing contracts/fixtures using bound color variables — none found (no contract JSON files are checked in at all yet). Real-world impact within this codebase is currently zero, but the fix is opt-in/zero-cost by construction (extra call only fires when a bound color is actually present), so it's safe to land ahead of any contract that needs it.
Closes #37
