Update Documentation

Audit and update all project documentation to reflect current code.

Doc Files to Update

File	Purpose
sdk/README.md	SDK user-facing docs — transforms, palette API, value ranges, type exports
cli/README.md	CLI user-facing docs — all subcommand flag tables, examples, defaults
cli/src/palette.ts	CLI palette showHelp() function and parseArgs() defaults
cli/src/index.ts	Main rampa --help text — subcommand list, IMAGE PALETTE section
cli/src/color.ts	CLI color subcommand help text and transform flags
AGENTS.md	Architecture guide — build commands, file map, conventions

Source Files to Read

File	What to check
sdk/src/index.ts	All SDK exports — types and classes
sdk/src/palette.ts	PaletteResult API surface, options interfaces, defaults
sdk/src/types.ts	All public type definitions
sdk/src/color-result.ts	Color transform methods, value ranges
src/engine/PaletteEngine.ts	Engine defaults — sampleSize, tolerance, bucket counts
cli/src/palette.ts	CLI palette parseArgs() defaults, flag list
cli/src/color.ts	CLI color transform flags

Audit Process

1. Read source files to understand current API surface and defaults
2. Read doc files to see what's documented
3. Diff — find stale defaults, missing features, removed APIs
4. Update — make surgical edits to fix gaps
5. Verify — CLI help text defaults must match parseArgs() defaults in the same file

Defaults to Track

These change occasionally and must be consistent across all docs:

Setting	Source of truth	Also appears in
Sample size	PaletteEngine.ts samplePixels default	sdk/palette.ts, cli/palette.ts parseArgs, SDK README, CLI README, CLI help
K-means tolerance	PaletteEngine.ts kMeansClustering default	sdk/palette.ts DominantOptions JSDoc, cli/palette.ts parseArgs, SDK README, CLI README, CLI help
Raw tolerance	PaletteEngine.ts buildRawPalette default	cli/palette.ts parseArgs, CLI README, CLI help
Dominant count	cli/palette.ts parseArgs default	CLI README, CLI help
ANSI count	PaletteEngine.ts buildAnsiPalette default	SDK README
L bucket count	PaletteEngine.ts DEFAULT_L_BUCKETS array length	cli/palette.ts parseArgs lBuckets, CLI README, CLI help
C bucket count	PaletteEngine.ts DEFAULT_C_BUCKETS array length	cli/palette.ts parseArgs cBuckets, CLI README, CLI help
H bucket count	PaletteEngine.ts DEFAULT_H_BUCKETS array length	cli/palette.ts parseArgs hBuckets, CLI README, CLI help
Contrast mode	sdk/src/contrast.ts default mode	SDK README, CLI README

SDK README Sections to Verify

• Color transforms (lighten, darken, saturate, desaturate, rotate, set, mix, blend)
• Value ranges (HSL s/l and OKLCH l use 0-1 scale, NOT 0-100)
• Ramp introspection (.at(), .colors() on Linear/Plane/CubeColorSpace)
• Palette extraction (palette(), dominant(), raw(), ansi(), group(), sortBy())
• Output formats (json, css, text)
• Type exports (all public types from sdk/src/index.ts should be mentioned)

CLI README Sections to Verify

• rampa color flags table (transform flags: --lighten, --darken, etc.)
• rampa palette flags table (all flags with correct defaults)
• rampa palette usage examples
• rampa lint flags
• rampa colorspace flags

Rules

• Release notes: Only include SDK/CLI changes. Never include site/editor/landing page changes.
• Site demos: Only update site/ if SDK API changes break existing demos.
• Value ranges: 0-1 scale for HSL s/l and OKLCH l. Format string output is unchanged.
• Help text: CLI showHelp() defaults must exactly match parseArgs() defaults in the same file.
