/**
 * @sharpee/platform-browser/channels/main — `main` channel renderer.
 *
 * Owner context: browser default. Implements ADR-165 §8 main-channel
 * behavior: append a `<p>` per entry to the `main` slot, with
 * decorations preserved.
 *
 * The `main` channel is append-mode; `value` is a `MainEntry[]`
 * (array of new entries this turn). Each entry becomes one `<p>`.
 * Entries with `tight: true` get a `main-entry--tight` class so CSS
 * can collapse the inter-paragraph margin against the previous entry.
 *
 * `onClear(target)` empties the slot when a `clear` event with a
 * matching target arrives (ADR-165 §4 step 2).
