Release version 1.2.5 - Parent product default pricing and UI enhancements

Added:
- Parent product default pricing for variable products - set tier/package pricing once on parent, variations inherit unless overridden
- Hide empty table headers in admin until pricing rules are defined

Technical:
- Added parent fallback logic to get_tier_price() and get_package_price() methods
- Created helper methods get_packages_with_fallback() and is_restriction_enabled() in cart class
- Updated all cart methods to support parent product defaults
- Added CSS :has() selectors to hide table headers when tbody is empty
- Fixed cart pricing calls to pass correct product ID for fallback resolution

+## [1.2.5] - 2025-12-30
+
+### Added
+
+- **Parent Product Default Pricing**: Variable products can now define tier and package pricing at the parent product level that applies as defaults to all variations. Individual variations can override these defaults with their own specific pricing. This makes it much easier to set up pricing for products with many variations - set defaults once on the parent, then only customize the variations that need different pricing.
+
+- **Hide Empty Table Headers**: Table headers for tier and package pricing in the admin area now automatically hide when no pricing rules are defined. This creates a cleaner interface when starting to configure a product, showing only the helpful empty state message and "Add" button.
+
+### Technical Details
+
+**Parent Fallback Implementation**:
+- Modified `WC_TPP_Frontend::get_tier_price()` and `WC_TPP_Frontend::get_package_price()` to fall back to parent product pricing when variation doesn't have its own pricing
+- Updated `WC_TPP_Cart` to use helper methods `get_packages_with_fallback()` and `is_restriction_enabled()` for consistent parent fallback behavior
+- All cart validation, quantity restriction, and display methods now support parent product defaults
+- Fixed cart pricing calls to pass parent `$product_id` instead of `$effective_id` for proper fallback resolution
+
+**CSS Enhancement**:
+- Added `:has()` pseudo-class selectors to hide table headers when tbody is empty
+- Leverages existing empty state message styling for consistent UX
+
+**Backward Compatibility**:
+- 100% backward compatible - existing products continue working as before
+- No database migrations required
+- Variations with specific pricing take precedence over parent defaults
+
+### Changed Files
+
+- `includes/class-wc-tpp-frontend.php` - Added parent fallback logic to `get_tier_price()` and `get_package_price()` methods
+- `includes/class-wc-tpp-cart.php` - Added helper methods `get_packages_with_fallback()` and `is_restriction_enabled()`; updated all cart methods to support parent fallback; fixed pricing calls to use correct product ID
+- `assets/css/admin.css` - Added CSS rules to hide table headers when no pricing rules exist

+
+**Problem:** Admin table borders still visible despite `border: none` declarations in v1.2.3
+
+```txt
+Issue: WooCommerce's core admin CSS has higher specificity border rules
+Location: assets/css/admin.css
+Symptom: Tables still showing borders in product edit screens
+```
+
+- **Root Cause:** WooCommerce's default admin CSS uses highly specific selectors that override simple `border: none` declarations
+- **Failed Approach (v1.2.3):** Adding `border: none` to table elements without `!important`
+- **Successful Fix (v1.2.4):**
+  - Added `!important` flags to ALL border removal rules
+  - Added `border-collapse: collapse !important` to force borderless styling
+  - Targeted all table structural elements: `table`, `th`, `td`, `thead`, `tbody`, `tr`
+- **Lesson:** When overriding WooCommerce core CSS, `!important` is often necessary due to high specificity in core styles
+
+**Problem:** Help icon positioned at right edge instead of next to label text
+
+```txt
+Issue: WooCommerce help-tip uses float: right positioning
+Location: assets/css/admin.css (checkbox/label layout)
+Symptom: Help icon appearing far from label text at container edge
+```
+
+- **Root Cause:** WooCommerce's default `.woocommerce-help-tip` styling uses `float: right`
+- **Failed Approach (v1.2.3):** Simple margin adjustments without changing positioning model
+- **Successful Fix (v1.2.4):**
+  - Removed float positioning: `float: none`
+  - Changed to `display: inline-block` with `vertical-align: middle`
+  - Wrapped label and help-tip in flexbox container: `display: inline-flex; align-items: center`
+  - Controlled precise spacing with margins (checkbox: 12px, help-tip: 6px)
+- **Lesson:** Overriding float-based layouts often requires changing to flexbox for proper control

+#### CSS Specificity and WooCommerce Overrides
+
+**CRITICAL LESSON from v1.2.4:** WooCommerce's core admin CSS uses high-specificity selectors that require `!important` to override.
+
+**Problem Symptoms:**
+- CSS rules not applying despite correct selectors
+- Styles work in simple cases but fail with WooCommerce elements
+- Browser DevTools shows rule crossed out or overridden
+
+**Diagnostic Steps:**
+1. Inspect element in browser DevTools
+2. Check "Computed" tab to see which styles are actually applied
+3. Look for crossed-out rules in "Styles" tab (indicates override)
+4. Check selector specificity - WooCommerce often uses complex selectors
+
+**Solution Patterns:**
+
+**For Table Styling:**
+```css
+/* ❌ This will likely be overridden */
+.wc-tpp-tiers-table {
+    border: none;
+}
+
+/* ✅ Use !important for core WooCommerce overrides */
+.wc-tpp-tiers-table,
+.wc-tpp-tiers-table th,
+.wc-tpp-tiers-table td,
+.wc-tpp-tiers-table thead,
+.wc-tpp-tiers-table tbody,
+.wc-tpp-tiers-table tr {
+    border: none !important;
+}
+
+/* ✅ Also use border-collapse to prevent cell borders */
+.wc-tpp-tiers-table {
+    border-collapse: collapse !important;
+}
+```
+
+**For Float-Based Layouts:**
+```css
+/* ❌ Float positioning is hard to control precisely */
+.woocommerce-help-tip {
+    float: right;
+    margin-left: 10px;
+}
+
+/* ✅ Use flexbox for precise control */
+label[for="_wc_tpp_restrict_to_packages"] {
+    display: inline-flex;
+    align-items: center;
+    gap: 0;
+}
+
+.woocommerce-help-tip {
+    float: none;
+    display: inline-block;
+    vertical-align: middle;
+    margin-left: 6px;
+    margin-right: 0;
+}
+```
+
+**General Rules:**
+1. **Always test in actual WordPress admin** - browser preview may not show WooCommerce's CSS
+2. **Target all related elements** - tables require styling on `table`, `thead`, `tbody`, `tr`, `th`, `td`
+3. **Use `!important` sparingly but don't fear it** - sometimes it's the only way to override WooCommerce core
+4. **Prefer flexbox over floats** - gives better control over alignment and spacing
+5. **Check across browsers** - table rendering can vary between Chrome/Firefox/Safari
+
+**When Styles Don't Apply:**
+- First verify selector is correct (DevTools should show rule, even if crossed out)
+- If selector is correct but crossed out, increase specificity or add `!important`
+- If selector doesn't appear at all, check file is enqueued and cache is cleared
+- Use browser's "Inspect" right-click to see exact element structure

 2. ~~Bug 2 in v1.2.3: Increase the margin between checkbox and label and put the help icon right next to the label, not at the right border~~ ✅ **FIXED in v1.2.4** - Increased checkbox right margin from 8px to 12px. Repositioned help tip icon to display inline right next to the label text using flexbox layout with `display: inline-flex`, removing float positioning that caused it to appear at the right edge.
 
-##### New Features
+##### Planned Enhancements for v1.2.5+
 
-1. Create different, selectable templates for tierprices and packages to use in the frontend. Make the new templates selectable globally on the settings-page, not per product.
+1. Hide the table-headers in admin area until a tier or respectivly a package price is defined.
+
+2. Make it possible to define tier or package prices on variable products in the parent product as a default for that product and all variants of it unless a variant has its own tier or package prices.
