Caldera. Forge fire on warm limestone.

Primary action buttons, featured stat cards, key visual highlights — the only aggressive chromatic accent; its vivid saturation against warm grays creates urgency without needing supporting decorative weight

Hero halftone gradient base, single secondary card surface — appears almost exclusively in the hero dot pattern and one standout card; never used for controls

Tag and category badge backgrounds, small highlight washes — the soft yellow that labels blog post categories and program announcements

Primary text, headings, link text, button borders — near-black with a barely-warm cast matching the canvas warmth

Page canvas, dominant background — the warm medium-gray that grounds every section; slightly darker than card surfaces to create subtle figure/ground separation without shadows

Card surfaces, content block backgrounds, secondary button fills — the lighter warm off-white that lifts elements off the page canvas

Dark-section text, input text on dark backgrounds, high-contrast overlays — pure white used only where maximum contrast against dark surfaces is required
