/**
 * TTS-249 (I2 / A1): frontend stylesheet for the light-DOM player (player 1).
 *
 * Player 1 renders into the light DOM (so WordPress core's Additional CSS can
 * style it), which means its CSS must NOT be a JS-injected <style> tag in the
 * page (wp.org bars inline <style>/<script> in output). Instead:
 *   - the selector-based / stateful / layout rules live here (enqueued via
 *     wp_enqueue_style), and
 *   - the dynamic per-button values (colors, size, border, margins, icon
 *     visibility) are passed as CSS custom properties + inline style="" on the
 *     button/wrapper by text-to-audio-button.js (a style ATTRIBUTE is allowed;
 *     only <style> TAGS are flagged).
 *
 * Players 2-6 (Pro) keep their own shadow-DOM <style> — that's isolated and
 * never appears in the page's light DOM, so it isn't a page-level concern.
 *
 * Selectors are class-scoped (`.tts__listent_content`). The base box/visual
 * props are applied inline on the button element (highest specificity, beats
 * theme rules); the colour-critical hover rules below use !important so theme
 * `button:hover{}` rules can't override them.
 */

/* Defensive typography reset — neutralise the few inheritable props a theme's
   `button{}` / global rules could bleed into the light-DOM button. Box/visual
   props are set inline on the element and already win. */

/* TTS-249: the player host is a custom element (`<tts-play-button>`), which the
   UA renders as `display: inline` by default. Inline elements IGNORE `max-width`
   and `margin-inline: auto`, so block-theme "constrained" layouts (Twenty
   Twenty-Five and every other block theme, plus classic themes' content wrappers)
   could not limit the player to the content width — the width:100% button then
   stretched to the full content container (e.g. 1590px) while the post text stayed
   at the ~645px content column. Promoting the host to a block element lets the
   theme's own constrained-layout rules (max-width + auto margins) apply, so the
   player aligns to and matches the content column on any theme. The old player
   had a block-level wrapper <div> that provided this; flattening the DOM removed
   it, so we restore the behaviour on the host itself. */
