Add an opt-in `sourcemap?: boolean` option that emits an inline source map (data URI appended as `//# sourceMappingURL=...`) when set to `true` (default: `false`). esbuild adjusts mappings to account for the banner automatically.
Add an opt-in `sourcemap?: boolean` option that emits an inline source map appended to the output when set to `true` (default: `false`). When enabled, feed the banner through PostCSS as a `/*!` important comment so cssnano preserves it and the inline source map line offsets stay correct.
…ching Add the new `sourcemap` option to the createStyleCompiler and createScriptCompiler sections in both the English and Japanese READMEs, and add a "Switching options per command" subsection showing how to branch on `process.argv` to vary compiler options between `kamado server` and `kamado build`.
Extend `sourcemap` from `boolean` to `boolean | 'onServer'`. When set to `'onServer'`, the inline source map is emitted only while kamado runs in serve mode (`context.mode === 'serve'`).

…mmand example Add the `'onServer'` value to the compiler sourcemap descriptions, and replace the `process.argv`-based per-command switching example with a sourcemap-only example that relies on the new built-in `'onServer'` value.

Previously the banner was prepended through PostCSS only when sourcemap was on,
and appended verbatim after processing when it was off — so cssnano touched the
banner in one path but not the other, producing slightly different output.
Always feed the banner into the PostCSS input via a new normalizeBanner() that
coerces it into a `/*! ... */` important comment, so cssnano preserves it in
both paths. The sourcemap option now only toggles `map: { inline: true }`.
Also notes that enableSourcemap is fixed for the lifetime of a command.
