/* Meal Prep Planner — public stylesheet (v1.0.1)
 *
 * v1.0.1 — CSS specificity hotfix:
 *   Raised `.mpp-input` / `.mpp-input--week` / `.mpp-select` to
 *   `.mpp-app input.mpp-input` / `.mpp-app input.mpp-input--week` /
 *   `.mpp-app input.mpp-select` / `.mpp-app select.mpp-select` so they
 *   beat the PenciDesign / pennews theme's `input[type="text"]` and
 *   `input[type="number"]` rules. Live QA on v1.0.0 showed 38 of 47 plugin
 *   inputs computing to 12px on that theme; v1.0.1 raises them to 14px
 *   (week grid) and 16px (grocery / batch / leftover forms). No markup
 *   change, no behavior change.
 *
 * v1.0.0 design direction: align with the released KnifeKettle plugin
 * family (Kitchen Converters v1.0.4, Baking Calculator Suite v1.0.13,
 * BudgetFlow Pro v1.3.6, Recipe Cost Calculator v1.0.4). Same indigo
 * accent #4f46e5, same slate text scale, same light slate page
 * background, same white cards with soft borders, same solid-indigo
 * active tab, same indigo-gradient result card.
 *
 * IMPORTANT — sizing:
 *   Explicit px values, not rem, because the PenciDesign theme sets
 *   html { font-size: 10px }. Using rem would shrink every element
 *   to ~60% of intended. All text meets the 13px floor; controls use
 *   16px (matches the family and prevents iOS auto-zoom on focus).
 *
 * v1.0.0 design rules:
 *   - Light theme ONLY.
 *   - Container max-width 1180px on desktop.
 *   - Page background slate-50 (#f8fafc) on the .mpp-app root.
 *   - Header is a white card with 14px radius top corners, attached
 *     to the tab strip (no border between them).
 *   - Tab strip is a white card with 1px slate-200 border; tabs use a
 *     flex-wrap pill pattern.
 *   - Active tab is solid indigo #4f46e5 with white text.
 *   - Inactive tabs are transparent with slate-600 text, slate-100
 *     on hover.
 *   - Section cards are white, 14px radius, soft shadow.
 *   - Result card uses a light indigo-50/100 gradient with indigo-900
 *     text and a soft indigo shadow.
 *   - Validation message is a soft red card #fef2f2 with #fecaca
 *     border and #991b1b text.
 *   - Mobile-first; stacks vertically below 720px.
 *   - All selectors scoped under .mpp-app.
