+<!-- Project idea: Quote + Color Generator
+
+Build a tiny page with one button: every click changes background color and shows a random motivational quote.
+
+How you can do it:
+
+Keep 2 arrays: one for colors, one for short quotes.
+On button click, generate random index for both.
+Update page background and the text content.
+Add one small rule: don’t repeat the same color twice in a row (you already know this concept).
+Why this boosts confidence:
+
+Super short build time (15-25 min).
+Uses DOM + arrays + random + condition in one clean mini-project.
+Looks fun and “real”, so students feel progress fast.
+If you want, I can give you 5 more “15-minute confidence projects” in the same style.
+
+const quotes = [
+"Believe in yourself and all that you are.",
+"Small progress is still progress.",
+"Discipline beats motivation.",
+"Success is the sum of daily efforts.",
+"Stay focused and never give up.",
+"Your only limit is your mindset.",
+"Dream big, start small, act now.",
+"Consistency creates confidence."
+];
