tp/tp-palette.el
Kinneyzhang 49cb8d8062 Fix confirmed bugs in core ops and builtins/palette modules 
ops/core (B1-B8): tp-remove no longer drops 3rd+ properties; string
removal is per-interval via tp--map-intervals instead of smearing
position-0 props; tp-clear defaults bounds from OBJECT; (tp-get STR N N)
works like the buffer region form; no bogus (:key nil) from trailing
bare keywords; region form signals immediately on flat PROP/VAL args;
face-family prepend semantics extended to font-lock-face/mouse-face.

builtins/palette (B45-B51): Emacs 28.1 compat for plistp/subr-x;
display-buffer macros use a minor-mode keymap instead of mutating the
major-mode map; tp-link resolves palette colors lazily (theme-correct);
tp-palette-alist is the single source of truth (stale defvars dropped);
tp-headline handles integer heights; tp-space matches its documented
pixel spec; tp-parse-color accepts one-sided cons colors.

Test infra: fixture gains unwind-protect teardown via tp-layer-reset
(incl. transforms); file header/provide renamed to tp-tests; suite is
order-independent (verified with shuffled runs). Adds Makefile with
test/compile/clean targets.

334 tests green (280 legacy + 54 new regression tests).

;;; tp-palette.el --- Color palette definitions for tp.el -*- lexical-binding: t -*-
;; Copyright (C) 2024
;;; Commentary:
;; This file provides color palette definitions for tp.el.
;; Colors are designed to work well in both light and dark themes.
;; Each palette entry has the format:
;; (:fg (LIGHT-FG . DARK-FG) :bg (LIGHT-BG . DARK-BG) :border (LIGHT-BORDER . DARK-BORDER))
;;
;; Color scheme inspired by:
;; - GitHub Primer Design System
;; - Tailwind CSS Color Palette
;; - Material Design Color System
;; - One Dark / One Light themes
;;; Code:
(require 'subr-x) ; string-trim-right
