feat: click-bonus and global-multiplier upgrade tooltip variants (#121)

[4sh-dev]

Summary

Extends the rich upgrade tooltip system (shipped in PR #120) to the two upgrade types that were explicitly deferred: click-bonus upgrades and global-multiplier (booster) upgrades.

Changes

New pure selector functions (tooltipHelpers.ts)

• computeClickBonusTooltipData — computes current/future/delta click power for a click upgrade. Excludes combo (transient) but applies the max(1, ...) floor to match the real engine. Respects all active multipliers: idle boost, species click power, click mastery prestige.
• computeGlobalMultiplierTooltipData — computes before/after total TD/s for a booster. newTdPerSecond = currentTdPerSecond × booster.multiplier.

Updated ClickUpgradeTooltipContent.tsx

• Reads live game state from useGameStore to compute the click-bonus delta at hover time.
• Shows "Click bonus: +X TD/click" with yellow glow for unpurchased upgrades.
• Respects the no-prestige challenge mode (zeroes prestige bonuses when active).

New BoosterTooltipContent.tsx

• Reads live game state from useGameStore to compute before/after TD/s at hover time.
• Shows "Multiplies all TD/s: current X → Y TD/s" with violet glow for unpurchased boosters.

Updated BoosterCard.tsx

• Wrapped in Popover (matching ClickUpgradeCard pattern).
• Added ℹ️ ActionIcon for mobile tap trigger — opens/closes tooltip without hover.
• Tooltip dismisses on mouse-out / tap-outside (Mantine Popover default behaviour).

Test fixes in tooltipHelpers.test.ts

• 10 new unit tests across two new describe blocks for both selectors.
• Fixed 2 pre-existing failing tests whose expected values did not account for the neural-notepad self-synergy (+100%, ×2) that activates simultaneously with the x3 milestone at owned=50. Updated comments explain the correct maths.

Testing

• npm run test — 689 tests passing ✅
• npm run lint — clean (only pre-existing warnings in upgradeEngine.test.ts, not from this PR) ✅
• npm run build — clean ✅

Review Summary — PR #123

Verdict: ✅ Approved

What was reviewed

All 5 changed files across the tooltip variant feature: the two new pure selector functions in tooltipHelpers.ts, the new BoosterTooltipContent.tsx component, the updated ClickUpgradeTooltipContent.tsx, the BoosterCard.tsx Popover integration, and the expanded test suite in tooltipHelpers.test.ts.

What looks good

• Clean architecture: Selector logic is pure and lives in tooltipHelpers.ts, completely decoupled from React. Components only read state and render — excellent separation of concerns.
• Decimal handling: Both new selectors use break_infinity.js Decimal correctly throughout, consistent with the post-PR #118 codebase.
• Click-bonus floor logic: The max(1, ...) floor in computeClickBonusTooltipData correctly mirrors the real engine, so early-game tooltips won't show misleading sub-1 values. Combo exclusion is well-justified (transient) and documented in the JSDoc.
• Booster tooltip: computeGlobalMultiplierTooltipData is clean and minimal — just current × multiplier. Hard to get wrong, and well-tested.
• Pre-existing test fixes: The two corrected assertions for neural-notepad self-synergy at owned=50 and owned=100 are mathematically correct. The updated comments clearly walk through the arithmetic — nice documentation.
• Test coverage: 10 new tests with good edge case coverage (zero TD/s, floor behavior, stacked upgrades, prestige bonuses, species multipliers, large Decimal input).
• Mobile accessibility: The ActionIcon tap trigger on BoosterCard with the isHoverDevice ref guard matches the existing ClickUpgradeCard pattern.
• Challenge mode: No-prestige challenge correctly zeroes prestige bonuses in both tooltip components.

Minor notes (non-blocking)

• nit: The no-prestige challenge logic (activeChallengeId === "no-prestige" ? {} : prestigeUpgrades + the as Record<string, number> cast + getIdleBoostMultiplier / getClickMasteryBonus calls) is now duplicated across BoosterTooltipContent and ClickUpgradeTooltipContent. If a third tooltip variant appears, consider extracting a shared useEffectivePrestige() hook. Not worth a round-trip for two occurrences.
• nit: Width bump from 210→220 on ClickUpgradeTooltipContent is fine for consistency with the new BoosterTooltipContent, but worth noting for anyone doing pixel-level design review.

CI

No configured status checks on this repo (consistent with prior merges). Developer reports 689 tests passing, lint clean, build clean.

• 10 new unit tests across two new describe blocks for both selectors.
• Fixed 2 pre-existing failing tests whose expected values did not account for the neural-notepad self-synergy (+100%, ×2) that activates simultaneously with the x3 milestone at owned=50. Updated comments explain the correct maths.

Testing

• npm run test — 689 tests passing ✅
• npm run lint — clean (only pre-existing warnings in upgradeEngine.test.ts, not from this PR) ✅
• npm run build — clean ✅

Review Summary — PR #123

Verdict: ✅ Approved

What was reviewed

All 5 changed files across the tooltip variant feature: the two new pure selector functions in tooltipHelpers.ts, the new BoosterTooltipContent.tsx component, the updated ClickUpgradeTooltipContent.tsx, the BoosterCard.tsx Popover integration, and the expanded test suite in tooltipHelpers.test.ts.

What looks good

• Clean architecture: Selector logic is pure and lives in tooltipHelpers.ts, completely decoupled from React. Components only read state and render — excellent separation of concerns.
• Decimal handling: Both new selectors use break_infinity.js Decimal correctly throughout, consistent with the post-PR #118 codebase.
• Click-bonus floor logic: The max(1, ...) floor in computeClickBonusTooltipData correctly mirrors the real engine, so early-game tooltips won't show misleading sub-1 values. Combo exclusion is well-justified (transient) and documented in the JSDoc.
• Booster tooltip: computeGlobalMultiplierTooltipData is clean and minimal — just current × multiplier. Hard to get wrong, and well-tested.
• Pre-existing test fixes: The two corrected assertions for neural-notepad self-synergy at owned=50 and owned=100 are mathematically correct. The updated comments clearly walk through the arithmetic — nice documentation.
• Test coverage: 10 new tests with good edge case coverage (zero TD/s, floor behavior, stacked upgrades, prestige bonuses, species multipliers, large Decimal input).
• Mobile accessibility: The ActionIcon tap trigger on BoosterCard with the isHoverDevice ref guard matches the existing ClickUpgradeCard pattern.
• Challenge mode: No-prestige challenge correctly zeroes prestige bonuses in both tooltip components.

Minor notes (non-blocking)

• nit: The no-prestige challenge logic (activeChallengeId === "no-prestige" ? {} : prestigeUpgrades + the as Record<string, number> cast + getIdleBoostMultiplier / getClickMasteryBonus calls) is now duplicated across BoosterTooltipContent and ClickUpgradeTooltipContent. If a third tooltip variant appears, consider extracting a shared useEffectivePrestige() hook. Not worth a round-trip for two occurrences.
• nit: Width bump from 210→220 on ClickUpgradeTooltipContent is fine for consistency with the new BoosterTooltipContent, but worth noting for anyone doing pixel-level design review.

CI

No configured status checks on this repo (consistent with prior merges). Developer reports 689 tests passing, lint clean, build clean.

Merging via rebase.
