Doughnut clicker

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a 3D doughnut clicker game with the following specifications:

**Camera & Perspective:** Fixed 3D perspective camera positioned at a slight elevated angle looking down at the center of the scene. The giant doughnut is framed prominently in the center with a soft focus depth of field.

**Visual Style:** Soft, pastel 3D aesthetic with pink/purple gradient atmosphere. Use ACES Filmic tone mapping with warm lighting. The scene has a pink fog (color #f6a7cf) creating atmospheric depth. Lighting includes: a warm hemisphere light (sky #fff0d8, ground #8a5070), a bright directional key light from top-right, and a pink point light (#ff6fb1) as rim lighting.

**Main Doughnut (Clickable Object):**
- Large 3D torus at center (golden-brown pastry color #c77834, pink icing on top #ff78b7)
- The icing is a slightly smaller torus positioned on the front-top of the doughnut, scaled to 1.02x horizontally and 0.72x in depth
- 14 colorful sprinkles (white, yellow, cyan, green, orange, purple) randomly placed on the icing surface as small rectangular boxes
- The entire doughnut group is rotated 0.16 radians on X-axis and gently bobs up/down with a sine wave animation
- It slowly rotates left-right on Y-axis (subtle oscillation)
- When clicked, it scales up briefly (1.16x), adds a small Z-rotation wobble, and triggers a click sound effect

**Background Elements:**
- A semi-transparent dark purple circle (#5a2d5e, 14% opacity) behind the main doughnut as backing
- 18 smaller decorative doughnuts floating in the background arranged in a circular pattern around the scene at varying depths and radii (4.7 to 6+ units from center)
- Each mini doughnut has the same golden-brown base with a darker pink top ring
- Mini doughnuts slowly spin individually and the entire background group rotates slowly clockwise
- They gently float vertically with individual sine wave motions

**HUD Display (HTML overlay at top):**
- Centered rounded translucent panel showing:
  - "DOUGHNUTS" label
  - Large score number (current doughnut count)
  - Below it: "X / sec · Y / tap" showing passive income rate and click power

**Shop Panel (HTML overlay at bottom):**
- Dark purple/brown rounded panel containing three upgrade buttons stacked vertically
- Each button shows: upgrade name on left, description/effect, and cost (with doughnut icon) on right
- Upgrades are:
  1. "Sprinkle Grip" - "+1 per click" - Base cost 25 (grows by 1.42x per level)
  2. "Tiny Oven" - "+1 per second" - Base cost 75 (grows by 1.55x per level)
  3. "Mini Bakery" - "+8 per second" - Base cost 350 (grows by 1.68x per level)
- Buttons are disabled/grayed when player can't afford them
- Below buttons: "Tap the doughnut!" instruction text

**Core Mechanics:**
- Click/tap the giant 3D doughnut to earn doughnuts equal to your "per click" value (starts at 1)
- Each click spawns floating "+X" text at cursor position that fades and rises, then disappears after ~950ms
- Spend doughnuts to buy upgrades which permanently increase click power or passive income
- Passive income (per second) automatically awards doughnuts every second in the background
- Score display uses abbreviated numbers (K for thousands, M for millions)

**Controls:**
- Mouse/touch: Click directly on the 3D doughnut mesh (raycasting detection) to earn doughnuts
- Mouse/touch: Click upgrade buttons in the shop panel to purchase

**Polish Details:**
- Click sound effect (interface click sound) plays on doughnut clicks and purchases
- The doughnut pulses and scales when clicked or when upgrades are purchased
- Numbers are formatted with K/M suffixes for readability
- Responsive design that adjusts camera distance on mobile (narrower screens zoom out slightly)
- Smooth easing animations on all interactive elements
