/* Physics module stylesheet (plan 08: per-module CSS).
 * Holds the calculator-specific rules extracted from inline <style> blocks in
 * the Physics module views. Loaded only on the pages that need it via the
 * layout's @stack('module-css') + each view's @push('module-css').
 *
 * Left INLINE on purpose (not merged here) -- do not "fix" by re-extracting:
 *  - Any rule with Blade/PHP interpolation in a CSS value (e.g.
 *    dimensional-analysis-calculator's `content: "{{ $lang[4] ... }}"`).
 *  - Generic element/type or attribute selectors that would leak site-wide
 *    once loaded on every Physics page: `img`, `canvas`, `footer`, `label`,
 *    `textarea`, `[type="checkbox"]`.
 *  - `.calculator-box` rules (density/velocity/acceleration/wet-bulb): this
 *    class is the page-global calculator wrapper used well beyond Physics --
 *    same call as Construction's square-meter-calculator number-spinner rule.
 *  - `#onetw` (enthalpy/scale vs. velocity-calculator) and `.katex` /
 *    `.katex-display` / `.katex .katex-html` (cross-product / dot-product /
 *    velocity / instantaneous-rate-of-change): same selector, different rule
 *    bodies across files -- collision if merged.
 *  - `.result-card` / `.step` (dimensional-analysis / dot-product /
 *    projectile-motion): same selector, three different bodies -- collision.
 *  - `.gap-2` (velocity vs. acceleration) and `.input-unit` (dot-product vs.
 *    velocity's `.addedRows .input-unit`): same class, different bodies.
 *  - `.active` (watts-to-amps/density/velocity/acceleration/amps-to-watts):
 *    identical body everywhere it appears, but the class name is a common
 *    Bootstrap/nav state class used well outside these tab widgets -- too
 *    generic to safely load site-wide across all 23 pages.
 *  - resistance-calculator's resistor-color-band rules (`.black`, `.red`,
 *    `.blue`, `.white`, `.gold`, ... ): single-word generic "utility color"
 *    class names, too risky to hoist into a shared file.
 *  - instantaneous-rate-of-change-calculator's `#exampleLoadBtn` rule: only
 *    rendered inside an `@isset($detail) ... @endisset` block, i.e. it's
 *    conditional on runtime data, not a static always-on rule.
 *  - dimensional-analysis-calculator's 5 style blocks as a whole: large,
 *    apparently-shared "AI helper" widget boilerplate (modal/dropdown/toast
 *    style classes) with confirmed selector collisions against other Physics
 *    files (see `.result-card` / `.step` above) -- left fully inline rather
 *    than risk a mis-split.
