/* Title Tag Generator , tool-specific styles.
 * Composes shared primitives in code/assets/css/tools.css (.tool-form-card,
 * .mode-toggle, .quota-chip, .results-region, .history-region, etc.).
 *
 * Key gotchas the project has hit repeatedly and we guard against here:
 *  - .mode-toggle pill: shared rule hardcoded for data-mode="bulk"; we
 *    override with data-mode="topic"/"url" so the pill slides correctly.
 *  - [hidden] + display:flex/grid: every panel that uses display:flex/grid
 *    AND toggles via the `hidden` attribute needs a per-tool override.
 *  - .results-region card-stack inner padding: shared region has no
 *    padding (sticky-header dependency); a card stack inside needs its
 *    own padding wrapper.
