- 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

+## [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
+
+## [1.2.4] - 2025-12-30
+
+### Fixed
+
+- **Admin Table Borders (Critical)**: Fixed table borders still appearing in v1.2.3 despite borderless styling attempt. WooCommerce's default CSS was overriding `border: none` declarations. Added `!important` flags to all border removal rules and `border-collapse: collapse !important` to force borderless styling. Now all tier/package pricing tables (simple and variable products) display correctly without borders, matching WooCommerce's clean admin UI.
+
+- **Checkbox and Help Icon Layout**: Fixed help icon positioning and checkbox spacing issues from v1.2.3. The help icon was appearing at the right edge of the container instead of next to the label text. Increased checkbox-label margin from 8px to 12px for better spacing. Changed label layout from float positioning to flexbox (`inline-flex`) to keep help icon directly adjacent to label text. Added inline description hiding when tooltip is shown.
+
+### Technical Details
+
+**Root Cause - Table Borders**: WooCommerce's core admin CSS has higher specificity border rules that override simple `border: none` declarations. The solution required:
+- Adding `!important` to all `border: none` rules targeting tables, th, td, thead, tbody, and tr elements
+- Adding `border-collapse: collapse !important` to prevent cell borders from being visible
+- Comprehensive targeting of all table structural elements for complete border removal
+
+**Root Cause - Help Icon Position**: WooCommerce's default `.woocommerce-help-tip` styling uses `float: right` which positions the icon at the container's right edge. The fix:
+- Removed float positioning with `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 spacing with precise margins (checkbox: 12px right, help-tip: 6px left)
+
+### Changed Files
+
+- `assets/css/admin.css` - Added `!important` flags to all border removal rules; added `border-collapse: collapse`; increased checkbox margin to 12px; converted label layout to flexbox; positioned help-tip with inline-block; added inline description hiding

+#### 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

+### Release Package Creation - Critical Notes
+
+**IMPORTANT:** The zip command must be run from the **parent directory** to create proper archive structure.
+
+**Correct command (from `/home/magdev/workspaces/php`):**
+
+```bash
+cd /home/magdev/workspaces/php
+zip -r wc-tier-and-package-prices/releases/wc-tier-and-package-prices-X.X.X.zip wc-tier-and-package-prices/ \
+  -x '*/\.git/*' '*/.git/*' 'wc-tier-and-package-prices/.git/*' \

+  '*/.DS_Store' '*/Thumbs.db' '*/.vscode/*' '*/.idea/*' \
+  '*.sublime-*' '*/notes.*' '*/logs/*' '*/templates/cache/*' \
+  '*/composer.lock'
+```
+
+**Critical Exclusions:**
+
+- `*/wordpress/*` - MUST be excluded! The project has a symlink to WordPress installation that zip will follow, creating 129MB+ packages instead of ~430KB
+- `.git/*` - All git metadata (multiple patterns needed for reliability)
+- `.claude/*` and `CLAUDE.md` - Development documentation
+- `releases/*` - Prevents including previous releases in new ones
+- `composer.lock` - Not needed in production (vendor/ is included)
+
+**Expected Package Size:** ~430-431KB (383 files)
+
+**Package Size Alert:** If >1MB, exclusions failed (likely wordpress symlink included)
+
+**Verification Steps:**
+
+```bash
+# 1. Check size (should be ~430KB)
+ls -lh releases/wc-tier-and-package-prices-X.X.X.zip
+
+# 2. Verify file count (should be 383 files)
+unzip -l releases/wc-tier-and-package-prices-X.X.X.zip | tail -1
+
+# 3. Check for excluded files
+unzip -l releases/wc-tier-and-package-prices-X.X.X.zip | grep -E "CLAUDE\.md|\.claude/|\.git/|wordpress/"
+# Should return nothing (exit code 1)
+
+# 4. Verify version in package
