/* Cover Letter Creator — site styles.
 *
 * One light world. The app's store presence is a warm cream sheet with indigo headlines,
 * periwinkle accents and a purple CTA gradient, and a job-seeker reading 1,200 words about
 * resignation etiquette wants paper, not a dashboard — so the whole site, builder included,
 * stays light. The one dark moment is the ink-navy footer/CTA band, which is the brand navy
 * doing what it does on the store screenshots' wave motif.
 *
 * Tokens come from app.md's brand section: #FAF9F6 cream, #2A22B5 indigo, #4A55E8 periwinkle,
 * #2D7FF0 app-icon blue, #7C5CFC→#5C55F5 CTA gradient, layered blue waves.
 *
 * Every colour pairing below was measured (WCAG 2.x relative luminance), not eyeballed:
 *   ink #17153A on cream ............ 16.6:1   indigo #2A22B5 on cream ......... 10.0:1
 *   peri #4A55E8 on cream ........... 5.3:1    muted #5A5878 on cream .......... 6.4:1
 *   white on grad light #7C5CFC ..... 4.38:1   white on grad dark #5C55F5 ...... 5.16:1
 * The brand gradient's light end misses AA for normal white text by a hair (4.38 < 4.5), so
 * buttons that carry white text deepen that end one step to #6C59F8 (white 4.75:1 — the
 * button's worst-case point) while decoration (icon tiles, hero glow, the paper's top rule)
 * keeps the pure #7C5CFC→#5C55F5. App blue #2D7FF0 is 3.69:1 on cream: graphics only, never
 * body text — its text-carrying variant is #1B5AC8 (5.97:1 on cream).
