/**
 * Parse a free-form text blob into a cleaned color array.  Accepts:
 *
 *   1. **Hex codes** — `#rgb` / `#rgba` / `#rrggbb` / `#rrggbbaa`,
 *      with or without the leading `#`.  The alpha channel on
 *      4- or 8-digit hex is silently dropped.
 *   2. **`rgb()` / `rgba()` functions** — `rgb(255, 99, 71)`,
 *      `rgba(255,99,71,0.5)`.  Whitespace and percentage values
 *      are both accepted (matches CSS rules).  Alpha dropped.
 *   3. **CSS named colors** — the 30 most common (`red`, `tomato`,
 *      `coral`, `teal`, …).  A small curated set keeps the parser
 *      from silently accepting typos that look color-ish
 *      (`tan`, `peru` are in; `chartreuse1` is not).
 *   4. **JSON / JS array** — `['#f87171', 'red']`,
 *      `["#f87171","rgb(0,0,255)"]`, even a single-line
 *      `["red","blue"]`.  Bracket and quote chars are tolerated
 *      so a copy-pasted `[…]` round-trips cleanly.
 *   5. **Any-delimiter blob** — the parser scans the raw text for
 *      color-shaped substrings rather than splitting on commas,
 *      so a user can paste `rgb(255, 0, 0), #0f0, blue` and every
 *      piece lands.
 *
 * Malformed tokens are dropped silently (consistent with the
 * rest of the canvas's "paste messy text" UX).  Returns at most
 * `maxColors` entries; output is lowercased `#rrggbb` for stable
 * dedup and direct comparison with `BUILTIN_PALETTES`.
